    Indeed sir you are correct.

The question is not if Windows sends WM_COMMAND, but if the control handles WM_COMMAND.

    I should have stated it a bit more clearly. From my tests, the edit windows context menu for clip board operations does not send the WM_COMMAND message to the owning edit control window.
But i see you point, does the edit control do anything with WM_COMMAND messages? Either way wine edit control only handles clipboard operations for WM_COMMAND, which is incorrect.

And have you ever seen Windows send a WM_MENUSELECT to an edit control?
    Yes for the edit windows context menu it sends the message every time a menu item is highlighted.

I redid the patch and submitted it to wine. Did something a bit more logical, send the clipboard message based on return value of TrackPopupMenu.

Even though I usually frown upon static variables myself, can you explain why using a static variable here a bad idea?

Fairly certain the problems in edit.c, did tests on XP and edit controls do not receive WM_COMMAND from menu controls.

The question is not if Windows sends WM_COMMAND, but if the control handles WM_COMMAND. And have you ever seen Windows send a WM_MENUSELECT to an edit control?

edit.c is shared with wine. Also using a static variable here looks like
a bad idea.
I would think that the problem is somewhere else.
