Hi,
Somewhere along the line since 3.0.1 the logic of 'mouse capture' changed to 
have the concept of it being possible to have multiple buttons 'captured' on 
button down. When the capture count goes to 0 on mouse up, the mouse is 
'released'.

Unfortunately, this seems to cause problems with , say, Win32 pop-up/context 
menus as OSG is not 'releasing' the mouse to the pop-up menu. 

The 'fix' ( for me) was to revert to 3.0.1 behavior so that the 
::ReleaseCapture() is always called on 'button-up'. Just a heads up for 
others...

Andrew
