I have a GLCanvas inside a commercial docking framework that seems to use JSplitPane a lot. Whenever I drag the split divider on the Mac, the 3D view refreshes with the wrong proportions for a while, until eventually there is a reshape and it refreshes properly (and it always refreshes properly when releasing the mouse). This behavior is fine with me.

On Windows, however, as soon as the mouse is down on the divider (before even dragging it) the 3D view turns blank (a light gray) until the mouse is released. This happens even when the divider doesn't even affect the size of the 3D view. The 3D view is the only component in the application that has this problem.

Does anyone know why I get this behavior, and how I can get the Windows version to work the same way the Mac OS X version does?
