It sounds like a screen redraw problem. Do you have screenupdating set to
false?

I made a Excel workbook with some VB Forms. In Excel 2003 we have the
following problem: Everytime I change from Form, this Form remaines
totally
white. After a doubleclick the Form appears. Does someone recognize this
problem or has a solution?
