Until just recently, Excel 2007 performed just fine. However, I am not sure
if an Office update or a Windows update had any effect on it, but all of a
sudden I am having issues. Documents open fine, and there is no problem
moving around in them. But, now print preview is very slow opening and
closing and changing the font format (Bold, underline, size, etc) takes 4-5
seconds. Both of these were instantaneous until about a week or so ago. The
same features work just fine in Word. I am using Office 2007 Pro Plus on
Windows XP Pro SP3.
