If the problem persits with the rev. 493, please inform us and send us a example file where we can reproduce that bug.
It is still there. Please keep in mind that I am talking about opening and then immediately closing an XLS file with NO changes... just looking at it. If I do
make any changes, the file size appears to behave pretty much normal.
As for a file sample, every file I've tried does it. From a simple one to a fairly large one. I've verified that it happens on 3 PCs already running either MS Office 2002, 2003 or 2007 (using the older file version, not the new Office 2007 format.) When I use MS Office to try to duplicate the issue, the file sizes are unchanged. This is occurring on 3 XP PCs (US/English.) 2 are SP3 (one Pro and one Home) and one is still SP2 (Pro.)
