In one of our schools they are reporting the following. When a window has accidentally been moved partly off the screen (with some ofthe window still visible) you can't drag the window back onscreen. To fix it, I use Command-W to close the window, then when I reopen it, it's back onscreen. Still, I'm wondering why it won't let me drag it all the way onscreen.
I have not seen it yet but anyone have any ideas? This might relate to my previous post.
