Hi there, First post here. I have a game app that needs to have non-exclusive keyboard access and must continue rendering even if the Windows system menu is activated. Thing is because Windows runs its own message loop when a menu is activated, I can't do idle processing. Is there a way besides multithreading to render during a menu loop? Thanks

On entering the menu loop you could set a timer for your window and inside WM_TIMER invalidate your window (you do draw in WM_PAINT too?)
Don't forget to kill the timer again after leaving the menu loop (WM_ENTERMENULOOP and WM_EXITMENULOOP).

This won't be the same speed as in full action, but should suffice.
