I am running into problems when I either paste an image or insert an image in
Excel. I get selection handles, but the image is blank. I can only see the
image if I:
1) save the document and close/reopen Excel, or
2) I move the selction handles a smidge.
I have only run into this problem when I switched over to Windows XP
Professional. I never had this issue when I was running Windows 2000
Professional.

P.S. The images I try to insert are 8-bit .tiff images generated in a 3rd
party scientific software package.
