Hi,

It sounds like of the following two methods are failing:

M: windows-ui-backend select-gl-context ( handle -- )
     [ win-hDC ] keep win-hRC wglMakeCurrent win32-error=0/f ;

M: windows-ui-backend flush-gl-context ( handle -- )
     win-hDC SwapBuffers win32-error=0/f ;

To find out which one, paste the following in your listener before  
minimizing:

M: windows-ui-backend select-gl-context ( handle -- )
     "entering select-gl-context" show
     [ win-hDC ] keep win-hRC wglMakeCurrent win32-error=0/f
     "leaving select-gl-context" show ;

M: windows-ui-backend flush-gl-context ( handle -- )
     "entering flush-gl-context" show
     win-hDC SwapBuffers win32-error=0/f
     "leaving flush-gl-context" show ;

Hit all restarts as they come up. Then try minimizing the window, and  
look at the traceback window again. The 'show' calls have the effect  
of inhibiting tail call optimization so you'll see which function  
called win32-error=0/f.
