Exactly. You need to add a FrmSetActiveForm after your FrmDeleteForm, so
that there's a valid destination window/form for the drawing system to
target.
This is another example of where the debug rom tells you of a problem, and
the release rom makes a guess as to what the right thing is. By using the
debug rom you can spot and thus prevent potential problems.
