I've a problem with the CApp::OnIdle()-routine:
In my SDI-App I installed an OnIdle() that works perfectly. Now I want to show a fullscreen-animation after a button is pushed and I want to use the OnIdle -routine to check for updating the (full) screen (20Hz or so). Therefore I create a new Wnd (with WS_POPUP|WS_MAXIMIZE|WS_VISIBLE style and all the stuff) and draw a bitmap to it. That's ok. But from then on my OnIdle() won't be called unless I move the mouse or press a key. As far as I found out this behaviour depends on the size of the created Wnd. If the mouse isn't in the client-area of the new Wnd during the creation, OnIdle is called. But only as long as I don't move the mouse(!) (no matter if inside or outside the new Wnd). Keypressing is ok.
Has anyone an idea of how to work around that?
