Intermittent startup error -- inverted worksheet window in Excel 2
 

Occasionally when I start Excel 2007 the app opens with the window inverted.
The status bar that SHOULD be on the bottom of the window (with the zoom
slider on the right) is at the TOP of the window. There is nothing at the
bottom -- no ribbon, no pearl, nothing. There are no gridlines -- the
worksheet is utterly unusable and I have to click the Excel worksheet icon in
the taskbar at the bottom of my monitor and click "close" to exit out of
Excel (as there is no other way to do it). Then I restart Excel and usually
it fires up fine on the restart, with ribbon, status bar, pearl etc in the
right place. This is unpredictable, but it happens every few days on my
machine. I've tried to do a "repair," from the install disks, but that has
not resolved the problem.

Is this a known bug or something no one has ever seen before? I've got a
screen shot of the window that I'm trying to describe, but I don't seem to be
able to post it here.

Thanks!
