I recently installed Powerplan7 Assistant for my mac
Anyway, I had to uninstall (doesn't support uninstall well) and now the icons in the notification area in bottom right corner have no borders. i.e., when I click on a button or the "show hidden icons" (the little up arrow) there is no border around the menus.
I don't have any normal pictures to show you (b/c mine doesn't work!), but if you have windows 7, just click on any of your notification buttons in the bottom right corner.
Attached it picture
