Okay, I've found my mistake. In the win32lib routine called 'popup'
find the line ...

   BBox = ScreenToClient(findParent(lRelId), BBox[1], BBox[2])

and change it to ...

   BBox = ScreenToClient(parent, BBox[1], BBox[2])

Then call it using 

  popup({mymenu, self}, x, y)

where 'self' is the id of the control that gets the right button
event.
