Summary: Right mouse button up message not sent
           Product: Wine
           Version: 20050524
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-user
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I've been working on getting WeatherScope running under wine. (Freely
available at:
http://sdg.ocs.ou.edu/builds/final/win/WeatherScope/WeatherScope-1.3.exe)
It's becoming quite usable, but there is an issue with the mouse I'm trying to
shake out.  In the program, when you right click on an object and bring up a
context menu, after selecting an item from the menu, the object behaves as
though you are holding the left mouse button and dragging the object around. 
This is especially annoying if you select the properties item from the menu.
This pops up a dialog box, but you can't interact with the dialog box because
the object still essentially has control of the mouse.  Double clicking the
object, which also brings up the properties box, does not produce this
problematic behavior.

Looking at a +msg, +message log, it looks like X sends a right button up
message, but this message is never dispatched.  I'm guessing this is because a
popup menu is engaged.  My guess is that since the button up is never sent, the
program thinks the user is dragging the object.  If I knew where to look it in
the Wine source, I'd try to see why the message isn't dispatched.  At any rate,
this behavior is not observed on Windows.
