We just upgraded our company to Office 2007 Pro this week and we are having
lots of problems with the stability of Excel. We are working with the same
spreadsheets that ran flawlessly in Excel 2003 but now Excel is locking up
almost every 10 to 15 minutes. We are seeing this response on all of our
workstations. Each workstation is a dual processor machine with 4 gig of
memory, 400gig hard drive which is generally about 50% full, and an Nvidia
7800gtx graphics card.

We are also having problems with the plots which are unbeliveably slow to
redraw. Just getting the program to respond after clicking on a line can
take 3 or 4 minutes. Granted we often have 4 to 5 lines with 20 to 30
thousend point each, but those same spreadsheets worked like a dream in Excel
2003. I cant even remember the last time Excel 2003 locked up or crashed
with the same class of spreadsheets.

We have gotten all of the Microsoft updates but that has not helped. With
this kind of performance, the program is just not useable. Has anyone found
a way to make the program more stable or respond faster? If we cant find a
solution we will have to go back to Office 2003 until these problems are
fixed.
