Syslinux - Mar 2006 - PXE Linux (Simple Menu) freeze after pressing 23 times return

Yes it sounds silly, but its true. 

I made a menu with some submenu with the simple menu system.
After pressing 23 times return to get into the submenu or back to the
mainmenu it freeze. 
I think this is a bug of syslinux. I tried it on 3 different PC/Servers
always the same effect.

Here is my default and one of my submenu files:

default:
