------- Additional Comments From mike@theoretic.com 2004-10-02 10:08 ------- I've implemented LockWindowUpdate, but I expect the app attempts to lock the desktop window which will require special-casing (yes, this would prevent *all* drawing to the screen). Unfortunately the patch isn't applied, it's blocking on inter-process invalidation.
