Hey, I'm a new member, and I looked around - but couldn't find any solution to this issue. If there is, please redirect me. At a random time months ago (I cant pinpoint what triggered it) certain windows started to make themselves half-opaque when inactive. They seem to be "cocoa" applications (though I'm not sure the exact definition of that). The windows that are effected are: Skype v2.8.0 (chat windows only, not main 'buddy list') iMovie iPhoto... I think there are more, I can't figure out which though. I'll update. The windows that are (surprisingly) NOT effected are: Windows Live Messenger v7.0.2 Textedit Microsoft Word 2007 Firefox v3.6 I have the program named "Afloat" and it seems to be inconsequential to the problem. Any help would be GREATLY appreciated! This is quite annoying.
