The previous change is not enough, as WM_KILLFOCUS can apparently be sent to the window losing focus after WM_ACTIVATE has been sent to the window gaining focus. Try using WM_SETFOCUS instead, as that has the correct ordering and seems more logical. The test "!pWin || !pWin->overrideRedirect" is confusingly written: It's true if: (a) pWin is NULL (= X window doesn't exist, shouldn't happen), or (b) pWin->overrideRedirect is FALSE i.e. the intended effect is "don't give focus to override redirect windows" There seem to be some cases where this still isn't quite correct: A reproduction isn't known, but it seems to be related to minimizing a maximized Windows window, and having window activation move to a maximized X window beneath it.
