I've investigated it further. You're right. I'm not really able to drag as long
as the popups exists. The problem occurs on a popup AFTER I drag the form. The
popup appears at the location of the form BEFORE it was dragged.

I was intent on having the popup disappear by itself after the cursor left the
input object, but that never seems to happen by itself, and since I know of no
command that will cause it to disappear programmatically, it remains until the
operator makes a choice by clicking on it. If there were such a command I could
make it disappear by change of focus and several other conditions. By the way
I'm using the fl_set_object_posthandler command to get the popups to work--a bit
like in your pup.c.

Yes, fl_get_mouse is something I hadn't thought of. I spent most of Friday
looking for a command that would give me the new position of the form after it
was dragged. This would enable me to recalculate the position where the popup
should be and position it there. But I couldn't find such a command. I'll try
your suggestion with the mouse. Thanks.
