Which version of Excel, OSX? Are any messages coming up when this
happens? Does it happen EVERY time, most times, some times?
Have you tried using Disk Utility to Repair Permissions? This may not
help, but it isn't a bad first step.
The fill color issue and the customize issue are 2 separate matters,
which suggests that it isn't a "bug". Instead it suggests that the
program is having trouble accessing certain files. Did you by any
chance have a "test drive" ver. installed which wasn't removed before
you installed the live ver.?
Try the Repair Permissions & post back with more detail if that doesn't
help |:>)
I'm running '04 & don't have X available so I'm not able to dig too
far. I did come across this earlier post on the same issue. You might
want to take a look at it. Hope it helps |:>)
