Every time I open a workbook in Excel (I have version in Office xp
Standard), it is listed again in the Project Explorer window in Visual
Basic. I.e. if I open and close a particular workbook 5 times, it will be
listed 5 times in the Project Explorer window. The only time the Project
Explorer window looses all these entries is if I shut down Excel and start
it up again. I'm sure it didn't used to be like this.

Anyone any idea of what I might have done to cause this, or know how to stop
it?
