Tried it, but doesn't work either. Restarted SC after diasbaled possible problem apps that could cause problems with the PrtScr button for the manual method, but it doesn't do anything, after I manually pressed the button and scrolled down the windows there is no Done button active. Maybe I'm the only one with this problem and something on my machine is the problem.
EDIT: I disabled OneNote now and it seems to work on FireFox now, even the manual mode, but its not a real good result. And it runs 3-4 times through the whole scrolling thing. Send WindowMessage and PgDwn method. Will try other methods, too. Will test Steam and report back.
Never had such problems with W7 and the older SC. But awesome program, I should donate more to this, keep up the awesome work.
