I also encountered this warning. Upon investigation I discovered that
FrmEraseForm actually sends a frmUpdateEvent to ALL the forms underneath the
form you are erasing. So for example, if you pop up three forms on top of
one another, then call FrmEraseForm on the top form, it should redraw the
bottom two forms.
I haven't tested this out, but consider this situation -- you don't call
FrmEraseForm for your last popup, then you popup another form which is
smaller than the last popup. Would there be a section of the background
form that was not redrawn?
