If ScreenUpdating is set to False it will do this.

Hi,

I was wondering why sometimes, when I have a userform on top of a sheet,
if
you move it by dragging the titlebar, it let's shadows behind it, so you
can't see what's on the sheet, and sometimes, it doesn't.

I have a userform, if just loaded, it doesn't let see what is behind it
when
you move it, but if you choose an item from a list on that form, suddenly,
you can move the form and see behind.

Is it a property or something like that? I would like to avoid the
shadow!

Thanks for your reply
