ok, to make it more clear. I noticed that we minimize to tray, not "exit" to tray, therefore, its always active in Alt-Tab for some reason. after that, if you select it thrue alt-tab, it won't properly minimize to tray! (check it out, unless its just me -_-) so my suggestion, is make the minimize button like usual, give a "exit" to tray, and then a right-click on icon and "quit" to really quit application. I dunno, its just annoying to see its in the alt-tab selection, and may solve that little glitch..!?
