Watch Don from San Diego, CA Comments

Don got a DMX controller for stage lighting. Leo says that DMX is very popular with TV broadcasting and stages because it's a computer network. He shouldn't use it with pyrotechnics, though, because errors can occur. There's also some limitations on distance. YouTube has a ton of great videos on how to use DMX.

Don says he has trouble understanding how to set it up because there's so many channels. Leo says that they are divided by color, intensity, etc. That's why there are multiple channels. Leo says that programming the lights will require a board that will assign numbers and light patterns to the channel.

Watch Dan from Woodland Hills, CA Comments

Dan has been getting messages to update Java, but he's worried about security. Leo says that since Dan uses Windows XP, there is a security issue because Microsoft doesn't support it anymore. Google will update Chrome, so it's a good idea to use that as his browser. But he shouldn't use Java unless he needs to. If he does need to use it, he should make sure he installs all security patches. He should disable the browser plugin as well, and he should run Windows as a limited user -- not as Administrator.

Watch Julian from Santa Barbara, CA Comments

Julian bought an Epson Workforce Printer with Precision Core. Can he use third party ink cartridges with it? Leo says that he thinks those solutions are a false economy. First, they may replace the head when they replace the ink cartridge. But if it's a multi cartridge printer, then they probably won't.

Some companies have chips in their ink cartridges that would prevent him from using them. The ink is fairly affordable on Epson printers, but at half the price, it depends on if he's happy with the results. Precision Core is special because it uses the smallest droplets in the industry. Third party ink may not be formulated well enough for it, which would run the risk of clogging the heads. And it takes a ton of ink to clear them out. If he's going through a lot of ink, it may be worth it. But Leo still thinks sticking with Epson ink is the best idea when it comes to Precision Core.

How about using a 4K TV as a monitor? Leo says even with 4K, it still won't look good. It's not as sharp when he's close up.

Watch Daryll from Palm Desert, CA Comments

Daryll's wife freaked out because she typed the first letter of her name into a computer she never used before and it said "Hi Gina" to her. Then she downloaded Google Chrome and it mirrored her sister's desktop 10 miles away. Leo says the only way that could have happened is if she was logged into it before, or her sister was.

Watch Karl from Pennsylvania Comments

Karl got a message that Facebook is going to start charging to like pages. Leo says it's fake. Facebook isn't going to do that. They make money on the traffic and advertising. They may charge to promote a page, but that's about it.

Watch John from Los Angeles, CA Comments

John is running iOS 7 on his iPhone 4 and he's having issues with iMessage logging him out frequently. Leo says that the iPhone 4 is several generations old and using iOS 7 is at the edge of it's capabilities. Leo advises going to the Apple Store to talk to a genius about it. He should call Apple and ask them as well. iMessage has been a problem almost from the beginning. But it should allow him to use standard SMS to send the message if iMessage isn't working. If he's also having issues with texting over SMS, then it could be on AT&T's end.

If he could upgrade to iOS 8, that would be a good idea, but with the iPhone 4, it's not recommended. He also will want to be sure to have all of his settings filled out, especially with send & receive. He may want to try resetting all of his settings by going to Settings -> General -> Reset -> Reset All Settings.

Watch Jay from Placerita, CA Comments

Jay has a CD ROM drive that's stuck and he can't get it open. What can he do? Leo says there's a tiny hole in the CD ROM that is an emergency release button. He can use a paperclip, stick it in and it will physically push the drawer out.

Watch Tom from Lake Havusu, AZ Comments

Tom's Nikon D40 was stolen. He'd like to get a new camera that has similar capabilities, but is smaller in size. Leo says that cellphones these days have more megapixels than that D40 did, and so long as he still has the lenses, the body is easily replaceable. The Nikon D7100 is an option, but since Tom wants a smaller and lighter camera, and he doesn't care about the lenses, a prosumer point and shoot may be the better option.

Leo suggests the Sony RX100. It has a huge 1" sensor for great low light shots and quality of image. And the lens in the RX100 is really nice. It's great for 'shutterbugging.' If he's willing to spend a bit more, then he could look at the Sony A7 Mk. II is one that Leo's using lately with a full frame sensor, and he can use those lenses. It's $2,000 though.

Another option is to go with a mirrorless, micro four-thirds system. The Olympus OMD line is a great option for that. The chatroom suggests the Canon G7X. Leo ultimately thinks Tom will be happiest with the Sony RX100 point and shoot, though.

Watch Joan from Anaheim, CA Comments

Joan has an HP computer running Windows 7, but she wound up with something on her system. Leo says that chances are she went on to install software and it's installed adware on her computer. Leo says that Microsoft displays a message if she wants to remove a system file, which may be what she's trying to do to remove that adware. On Microsoft's UAC popup asking to update the system file, Joan should say yes.

Also, from now on, she should run as a standard, or limited, user instead of Administrator. That way she'll have to input the administrator password every time something wants to be installed.
