why a popup-menu does not open at a new defined mouseloc?

[G.Wolfgang Gaich]

Hi Jacqueline,

thank you for your time and your suggestion.

I figured out that also a move command corrects the mouseloc for the
popup command.

set the screenmouseloc to globalloc(the loc of btn 1)
move me to the loc of me --(or move this stack to the loc of this stack)

Then the popup menu pops up at the loc of btn 1


Regards,

Wolfgang
