Context menus in REAPER gets considered as a top-level window

[chinatsu]

Clicking on a menu item spawns a floating window in the center of the screen. Holding down the mouse button lets me move selection in the menu in a rather offset (as if the menu had spawned by the cursor) way.

Letting go of the mouse button closes the menu immediately. Opening the menu through a hotkey such as Alt+O lets me at least move my mouse to the opened menu window (so the mouse offsets seem to be okay in this case).

I have a feeling this is related to some of the other issues already opened (such as #110, perhaps?), but I'm not entirely sure.
