I have developed an application in Excel 2002 and they have now decided
that they want it to run in Excel 2000.

What issues are likely to arise?

Is there any way I can work on the app on my PC, which has 2002 on it,
and know that it will run on 2000 with out problems?

Is there a list of compatibility issues between the two versions?

Right now, I cannot even save the app, from my PC, in the multi version
option from the SaveAs dialog - It tries to save it - gets to 16k - pauses
for ages (20+mins) - then tells me "Document not saved" without a reason.
The first time it did tell me that I would have to change the protection on
the VBA code, which I did, as a project which is protected for viewing
cannot be saved. I have managed to open the app on a PC with Excel
2000 and with changing the calendar control it appears to run fine except
for the sort function I used - some options were not acceptable.

I would appreciate any comments any one has to offer. Thanks.

Chrissy.
