11 * TODO: Some messages that are sent to the frame window are directly passed on to the client
12 * -> Get/PeekMessage never gets them as we return a dummy message for non-client windows
13 * (i.e. menu WM_COMMAND messages)
14 *
15 * TODO: Filter translation isn't correct! (for posted messages or messages that don't have
16 * a PM version)
17 *
18 * TODO: Flaw in our message handling; we don't handle posted/sent (by the app)
19 * system messages properly if removed from the queue with PeekMessage.
20 * e.g.
21 * PostMessage(WM_KEYDOWN)
22 * PeekMessage(any, PM_NOREMOVE)
23 * ...
24 * PeekMessage(WM_KEYDOWN, WM_KEYDOWN, PM_REMOVE)
25 *
26 * So what we really need is a complete win to os2 message translation
27 * in Post/SendMessage. Quite a lot of work though...
