migration issue - OpenText method crashes Excel.
 

Hi,
I have a problem that occurs only in Excel 2003, whereby a macro that
contains the "Workbooks.OpenText .." method is run, but before the "OpenText"
method is reached in the program execution, the user manually clicks on
another open program such as Windows Explorer or Outlook. Excel will then
crash when the "OpenText" method is reached. The problem does not occur in
Excel 2000.
Does anybody know a workaround?
Thanks,
Michael
