Thanks. I'll look through and see if I can find the flags that were used for the window in question.
If I'm reading this correctly the window in question was created with WS_POPUP WS_DISABLED WS_CLIPSIBLINGS, so that makes me think my most recent patch may be the right approach.
No, this patch does not fix it. But it seems to me it does not do what you say, if the window is with children this patch change nothing for it.
The patch checks for the WS_CLIPCHILDREN flag, and if that is not set then it ignores the known_child bool since that is only needed if WS_CLIPCHILDREN is set.
