I am running XP SP2 with GW 7.01 and Excel 2003

I am able to create new excel docs and save them to the library but
when I go to open them, Excel opens but does not show the spreadheet.

Also, GW (in the Activity Log) does not think that I've tried to open
the doc.

Any ideas ?

I am able to open it on a few othere PCs but only 2 of 15 so far can
open the file !!
