I couldn't find a thread talking about this specific issue, so here goes. I'm getting the feeling that my mission control is not working properly. When I go into mission control right now, I have my dashboard, desktop, mail, and ical as windows at the very top. I hover the mouse over ical, for example, and no iOS style X pops up to close that window, which I think is what is supposed to happen. I also read that there is a way to rearrange the order of the windows on top, excluding dashboard and the desktop, using the option key but I can't do that as well. Any ideas?
