probably there is some badly-written VBA somewhere (.XLA or Personal.xls or
....) which is modifying toolbars or menus but not resetting them when
closing.

On some of our PC, the Excel11.xlb file is very very big (20 to 50Mb) and
its size increase by 30k each time Excel is closed!!!
This have a very bad impact on Excel Performance especially at the closing
time
I know that we can delete the file and then get a new one that is 40k only
but how to stop the 30k increase mechanism? To which setting can be linked
this feature?

Thanks for your help
