Notify icon messages is not impressive MsgWaitForMultipleObjectsEx

I am using MsgWaitForMultipleObjectsEx()

for my message loop and Shell_NotifyIcon

for creating tray icons.

Here's the deal: whenever the tray icon sends messages to that owner window, the window will not receive messages immediately, instead they will queue until another type of message arrives ( WM_MOUSEMOVE

for example).

It looks like the messages from the tray icon for some reason won't get MsgWaitForMultipleObjectsEx()

out of the idle state, even though I'm calling MsgWaitForMultipleObjectsEx()

with a mask QS_ALLEVENTS

.

I am using WM_USER

+ ... for NOTIFYICONDATA::uCallbackMessage

, and I also tried using the "specific" value ( WM_MOVE

, ...). Did not help.

Has anyone faced this problem?
