Hi all, hoping someone may be able to assist with the following.

Have a fairly complex workbook with a number of macros and forms in place.

Today, on opening, I have encountered the following error message:

***
"Microsoft Excel for Windows has encountered a problem and needs to close.
We are sorry for the inconvenience.

If you were in the middle of something, the information you were working on
might be lost.

Please tell Microsoft about this problem.
We have created an error report that you can send to help us improve
Microsoft Excel for Windows. We will treat this report as confidential and
anonymous."
***

Nothing has been changed since the last time this was opened ok (I have sole
access at the moment) and the error message appears whether I open
Write/read, Macros Enabled/Disabled.

There's a lot of work in here that will be lost if I can't get back into it,
so I'm HOPING that someone may be able to suggest a method to get back into
it (at least to salvage parts), and also something that might be causing this
problem, so I can avoid in future.

The message does not offer any option to repair, restore to an earlier
version etc. There are only 3 options available:
Debug (opens a C++ Editor if installed)
Send Error Report (which sends, then directs to a MS page stating "sorry,
you're using Office 2000 so you're on your own")
Don't Send (about as much help as sending).

I know it ISN'T:
The size of the workbook (about 1.2MB)
The amount of code (I run workbooks with much,much more...)
The forms (they've been working fine for over a week, and haven't been
modified)
The macros (as it does the same thing when they're disabled)

ANY assistance or ideas appreciated, as I've not come across this one
previously, and really would prefer not to have to start again with this
one!!!

Thanks in advance
DS
