Problems running Excel under IE
 

I have an Excel file that begins with a Workbook_Open macro. The macro
makes only one sheet of the workbook visible, and displays a userform.
It all works fine running directly under Excel. However, when it runs
under IE (the normal way it is run here), the sheet that is supposed to
be visible is blank (or not loaded). Any ideas? I've tried doevents
thinking it might be a timing problem.
