Citrix Server closing Excel on save issue

Good Morning.

Can I please put out a quick question...
Does anybody use Excel over a Citrix network?

I use Excel/Word 2000 over a Citrix network and have many major issues.
My current one is that Excel shuts down randomly whenever I click save.
I have saved it as a new workbook and cut and pasted all data into a new session work book but it has done nothing.

Has anyone else had these problems?

I am not doing anything too technical. The spreadsheet was a multi-tabbed sheet but in a new document I took this down to one. I had a lot of formulas (averages and total) and cut and past the data as values so now there are no formulas. I have colour coded the document as I am looking at 7 data sets (3 months of data in rows across 7 columns).

The weirdest thing is... for instance... I just highlighted a 'totals' cell black with red text. Excel shut down. Went into it again and did the same and it shut down. Changed it to another colour, it stayed open.
I can put complex things in one cell and it behaves normally and do a simple change in another and it closes.

Does or has anyone else have these issues over Citrix and if so, what have you done to help resolve it?

Many thanks,

Damien
