Similar here - after a sub-menu opens and cursor moves further along parent 
menu 
the menu item selection suddenly jumps to the top and scrolls down the parent 
menu, see video;

Notice also flickering along the vertical intersection line of menu and submenu

Attached is a preliminary version that avoids loosing originally selected 
menuitem.
The idea is to inform the parent after child close that parent redraw will 
follow (rather than actual selection by mouse)

Thanks for updating Rodrigo.
However my demo app still displays the same problem of the jumping highlight 
(jumps to the last subitem) and also my hidden subitems are being displayed. I 
am using R274 AFAICS
Regards

The highlight still jumps for me in R277. The code is too complex for me to 
debug (sorry) but it seems that when a submenuitem is highlighted the submenu 
paints fine. When you move to the next menuitem the submenu is destroyed and 
the menu repainted with the highlight for each item set. Problem is the 
highlight is left on the bottommost menuitem instead of repositioning back to 
the item that was highlighted when the submenu was destroyed. Hope you can 
follow my explanation. Best regards

The problem reappeared on the computer of one tester, on my machine with the 
same code everything is OK. 

I can only think of uninitialized variable(s) as the primary cause.
