entering fullscreen on subclassed NSOpenGLView leaves empty window

Question

hello,

i have an application with 2 windows, one is a custom subclassed NSOpenGLView and one is displaying some standard cocoa user interace.

making the opengl view go fullscreen (only on one NSScreen) works by calling enterFullScreenMode and exitFullScreenModeWithOptions and supplying the right screen and setting NSFullScreenModeAllScreens.

but this leaves the previous window, where the opengl view was before, behind and empty. is this supposed to work this way? do i have to take care of this abandoned window myself (hiding and unhiding it) or am i missing something or not doing it right?

btw, i am only targeting Leopard. i thought i should mention this since fullscreen seems to always have been a hassle and even more on tiger...

thanks in advance!
