Sorry for jumping into the thread late, but I have
been looking into a probably related menu bug.
err:menu:MENU_FindItem Bad handle 01cf:(nil)
err:menu:InsertMenuA New menu item added to tree! hMenu 03c2, pos 16, flags 00000400,
id ffffffff, str ''
{ ID=0xffffffff, Typ=sep }
Intead of menu items I get separators with NULL buffers or buffer gets re-used
(whaterver garbage was there). This is similar to your problem.
The problem seem to be with the dymanic menu items, the MDI child windows
to be exact. MENU_FindItem can't find them (bad handle) and returns NULL,
this leads to the chain of events where they get replaced by "default values"
eg <<separator>> "contents of buffer"
I should add that the menu is fine at startup, but the problem occurs when you
modify it later ( in my case when I "reset defaults" ).
Why these handles are(have become) invalid is a mystery. It is the same
subdmenu handle that has been used on 15 menuitems previously, on the 16th
(and first MDI child) it is no longer valid. This failure corrupts/truncates/
the menu.
Presently looking at MDISetMenu(), MDIRefreshMenu()(stub).
