I'm suppose that this is inside a DO UNTIL FN BUTTON loop, as i can't see
where you check that the mouse is down (I see you grabbing the position).

perhaps you have actived the StickyMouse function, and this is
inteferring with your code?

But when looking thru my control panels - I can't find why to deactivate
it? Where is it? I find this useful but want to help Alain!

Someone! anyone!

PS. AFAIK what i call the StickyMouse is the AutoPullDown menus
and i believe that this is a hack on the mouseUp event. If you're
assuming your events in your code rather than explicitly polling them -
this could be where you come a cropper. (c'est-�-dire, l� o�
�a plante!).

Sorry for the french, but alain says that my Enlish is the most
incomprehensible of the list! This is probably 'cos i speak it worst
having had to speak french for so long... If others also think that
my english is too garbled then don't hesitate to mail me privately
and put me write :-)
