🚀 go-pugleaf

we have an application where a parent form calls a non-modal child form (ie: 
childform.show; ). In this childform, the user can scan forms which may be 
viewed.
The OK button will then save this image (by calling an appserver method via 
Tsocketconnection), then do a self.hide( );

Sometimes, the child form does NOT hide, which is very irritating for our 
client. Of course, this does not happen in run-time, so I added an audit log 
text file with a msg before and after the hide. Both msgs get printed --  
according to Delphi, this form is invisible.
As well, the only way to close it, is to close the parent form (where the 
Close method has a child.close; child.free calls), the parent still has a 
pointer at this child form !

The question is, what might cause this child form to intermittently NOT hide 
!? Could the window handle of this form be 'lost' while running the 
appserver method ?

If anyone has any ideas at all, I'd love to hear it
