After my machine has been running for awhile, when I open Excel 2007, no
workbook is visible. I just see the blue background. Yet the default 3-page
workbook is there, I can see it and the sheets listed in the VBA IDE. When I
open one of my own workbooks, it creates a new window and appears to open,
but again, only the background of Excel is visible. If I reboot the machine,
the problem goes away--the empty workbook is there when I start Excel, and my
own workbook is visible when I open it. However, after opening and closing
Excel a few times, the problem starts again. I've tried searching for this,
but "workbook" and "visible" are such common terms that I can't find any
relevant posts.
OS: Vista Ultimate x64; Office Pro 2007; all the latest updates are in
place.
