I am using excel 2000

I recently created a custom toolbar with 4 custom buttons but now cannot find the toolbar

I think this was caused by opening a file someone sent to me, which has re-set all my toolbars

How can I stop this happening

I have solved my problem, I have re-created my custom toolbar and made a back-up of excel.xlb, now I can overwrite excel.xlb with the back-up if somebody sends me a file that resets my toolbars
