Hi guys, (sorry if this has been brought up multiple times, but the problem seems to be so vague i cant think of a good keywords looking for this.) i just got my macbook few weeks ago and i'm struggling with this problem : sometimes when i start an application then minimize/hide/switch to other application, when trying to get back to it i cant seems to get the window to "maximize" back. this happens to many application, namely : ichat, iphoto, system preference etc... i know this application is still running because i can see the bluedot on the dock below its icon and the top toolbar still shows that application and its pulldown menu... however, clicking on the icon again, or goto expose, or go to cntrl-tab doesnt help maximize the window itself. another thing is- if i goto the application toolbar > windows, i noticed that "close" and "minimize" has been greyed out. i believe the person who posted this thread (http://forums.macrumors.com/showthread.php?t=458600 ) has the same issue, but unfortunately everyone seems to not being able to understand his problem properly (not sure if i did a better job) do lemme know if anyone has any leads or face similiar glitches. thanks! cheers, Ryan.
