Yesterday my Vista Ultimate install started to play up, and a quick search told me this was the place to help me.
Basically the UAC dialogue box will not appear. Whenever I try to install a program or change any setting vista deems as a potential security risk the screen goes dark and normally a dialogue box appears for me to allow or deny the action. However, the box does not appear any more, but the screen still goes dark and I cannot click anything. Also, the language bar sometimes pops up for some reason (UK English/Us English-I think it's the one that changes the keyboard country type). This makes me think it could possibly a display issue?
Anyway theres no way for me to accept it-Enter does not work, and I have to Ctrl+Alt+Delete out of it. I do have a dual monitor setup, but it's only recently that the problem has occured, it worked fine before. The monitors are of different resolutions...but I don't see how it could really be related?
Also, I have looked into ways to disable UAC, (such as the 5 at click here) , but all of them require me to accept the dialogue box first, which I cannot see...
Any comments/suggestions/help are appreciated, I like to think I know my way around most computer problems, but this one has me stumped and I cannot find any information about this happened to anyone else..I'm seriously considering going back to XP.
