Dear all, I'm currently trying to have a popup tooltip show over my main Open GL window. Naturally my Open GL window is constantly painting but I registered it as a WS_CLIPCHILDREN and WS_CLIPSIBLINGS style and subsequently my tooltip as a WS_CHILD window to this window. Even though I've done this, my tooltip is almost immediately painted over...? Similarly I have some owner drawn button controls in my window that do not get painted over although are registered in a similar fashion as children. Can anyone think perhaps of an easy way to work around this or where I may be going wrong? Kind Regards, James

Thanks for the replies, I'll probably try both and see which works out best.

Regards
