I am having a problem much like yours. When I try opening the problem file I
get errors and all formatting is gone.

I am curious, do you use multiple monitors and have excel opened twice (one
for each workbook?) Then after copy and pasting for a few minutes excel
starts acting strange and slows down. Eventually pasting data doesn't appear
in the destination cell. I am really dissappointed in Office 02007. Seems
like the new stuff out of Microsoft (Vista, Office 07, etc.) is even more
buggy that before!

Hi, I'm Marc. I am using the Windows XP operating system with Office 2007.

The problem I'm having is a perplexing one. Lately I have been copying and
pasting numerical information from one excel document into another. I'll be
going along and than all the sudden the eight rectangles in the "Styles"
category on the "Home" Tab will go bezerk. The first rectangle displays "--",
the second "--10", the third "--11", the fourth "--12", but anyways just
weird symbols that don't look normal. I than save my work to go do something
else but when I open the excel document back up, all of my formatting is
gone. The actual numerical information I inputted is still there but the
formatting is completely gone. It gets really frustrating because I than have
to start over only to have the same thing reoccur. I know this kind of sounds
off the wall but I've been trying to fix it and nothing seems to be working.
