OK, I think I see what's going on now. You're correct that the jumping
around issue is caused by the menu code. It's because each menu/submenu
"remembers" the last selected entry and the default entry only applies
the first time you visit a menu/submenu.

Try apply this patch ontop of the one I sent the other day and see if
the behaviour is more like what you were expecting,

diff --git a/com32/menu/menumain.c b/com32/menu/menumain.c
index 7c58979..db81346 100644

The problem is that this patch by itself is likely to break backwards
compatibility, as I'm sure people will be relying upon menu/submenus
remembering the last selected entry.

Could you fix this in your menu-generation tool?
