[GD-Windows] Out of window mouse up messages

[Brian H. <bri...@py...>]

I'm tracking drag state in my app, however I'm running into a problem
when the mouse button is pressed, the cursor is dragged outside the
window, and then the mouse button is released.  I never see the release,
which gets my app confused.

Is there a simple way of getting around this, or should I simply check
the mouse button state every time I get a move message to verify its
authenticity?
