Summary: Menu posting problem on dual monitors

Initial Comment:
This bug happens on Windows in dual monitor mode, when the second monitor is placed above the primary monitor. Note that this means that the second monitor has negative y coordinates.
When posting a menu on the second monitor (either from a menubutton or directly with tk_popup), the menu is actually displayed on the primary monitor.

The reason can be found in the procedures ::tk::MbPost and ::tk::PostOverPoint. These contains checks like:

	if {$y < 0} {
	    set y 0
	}

Which makes it impossible to post menus at negative y coordinates.

Message:
I just ran into this problem as well. Is there a work around? I put a large
monitor, connected to my docking station, above my laptop display. I
suspect this is a common arrangement (based on walking around cubes) so
whoever deploys Tk apps to work across multiple monitors will get dinged
for this bug.
