Can a mouseclick simultaneously send a message as it ends a "repeat until the mouseclick" loop?

Thanks, Jan.  When I checked out the mouseControl function it appears to
return the type and layer of the control.  While I could send a mouseUp to
the control by testing for it being under the cursor, what I need it for the
mouseUp to be sent on actually clicking the mouse from within the repeat
loop, not simply crossing over, or hovering over, the control region.  I'm
probably missing something, so please educate me.

Given that I have a pretty simple thing going on: On ShowWords... repeat
until the mouseclick... put word the random of gMyWords into fld myField...
other stuff... wait gtheTicks... end repeat... end mouseUp, how could I
better script the performance to be able to execute a new mouseUp without
having to waste one to exit the existing one without having to waste one?


Thanks again,
Mark
