I have build  new wx dll by applying these 2 patches on the wx263p2 code and have tested with revision 3295 (rather old !!!). these are the results : 
 - menus (with or without) icons alligned correctly
 - icons grayed out  in the menu as they should be
 - 90% of the icons are gone (due to keybinder)
updating my CB now to the latest revision, will adjust this post with the new results.
[EDIT : test finished]
with the latest svn revision 3516 : all is OK (all icons present) !!
