I bought my Coby Kyros 7034 tablet on eBay and I'm just now learning how to use it. I have NO owners manual, so I'm kindof flying blind a lot of the time. I bought two of these tablets to use as WiFi throttles on my HO gauge model railroad. For that' they work perfectly. But in playing around with them, I found out how much more you can do with them. One problem I have with one of them is that it used to boot to a screen lock that you could use your thumb to slide a lock icon over to an unlock icon. But now for some reason it no longer locks like it used to. It just boots to the desktop. In the settings area, under Security, I have the option "Slide" selected as the unlock motion, but the lock screen now never appears. Can anyone tell me why the lock screen doesn't appear any more? Thanks in advance!
