SUMMARY
When a window spans 2 physical screens, the location of a menu bar dropdown is sometimes difficult to get at unless the window is relocated to be mostly over left screen.

STEPS TO REPRODUCE
1. locate a window so it spans 2 screens
2. if window is mostly on left screen, dropdown appears directly below menu bar
3. if window is mostly on right screen, dropdown appears on left edge of right screen 

OBSERVED RESULT
[ screen 1  |  screen 2  |  screen 3 ]  I have 3 screens
[ window1 ] |            |           ]  Full window on 1 screen
[M          |            |           ]  menu dropdown OK
[       [ window2 ]      |           ]  window spans 2 screens (<=49%|>=51%)
[           |M           |           ]  menu dropdown appears on right screen [1]
[           |    [ window3 ]         ]  window spans 2 screens (>=51%|<=49%)
[           |     M      |           ]  menu dropdown OK
[           |         [ window4 ]    ]  window spans 2 screens (<=49%|>=51%)
[           |            |M          ]  menu dropdown appears on right screen [1]

[1] very difficult to mouse over it

EXPECTED RESULT
menu bar dropdowns should always appear directly under menu bar's left edge.
