downloaded 4 repositories last night............. while doing the zip files on the last one the box froze up. I couldn't do anything so I pulled the plug and rebooted. after that it was fine. then I noticed all the new video apps was already enabled. I didn't get to choose which ones I wanted......when I went on to the program apps.... I could not enable the ones I wanted. I proceeded to uninstall every video app I didn't want. I was told some of the apps could not be uninstalled or disabled! I guess I could do a clean install but I finally got it full of stuff I like. what would be causing me to not be able to enable program apps?
