Just happened 2 hours ago.....
Vista tutorial shortcut changed image and then reverted back to original image a little while later........
Correction from my original post.....
This happens only
when I click at vistax64 forums
, both vista and win 7.
It does not happen in other shortcuts.
Yes, sometimes, only sometimes, the screen flickers, and that also happens ONLY when I click at vistax64 forums.
