Ok, so "New Posts" screen is the issue. I have no idea what's different about how it displays versus any other screen so I'll have to find a way to duplicate the problem on some piece of hardware we don't currently have. Can you drop your resolution as a test to 1280x1024 and tell me if that clears it up on that specific screen?
As far as the UserCP (User Control Panel), they now call it "Settings" in vBulletin v4. Check the attached pic and I've shown two ways I've found (so far) of accessing that area. :lol:
