OpenEuphoria

I have a program that uses popup menus with sub menus. the sub menus work fine, but when I mouse over the last menu item I get the following error.

c:\euphoria\win32lib\include\Win32Lib.ew:23698 in function fDoMENUSELECT()
subscript value 11 is out of bounds, reading from a sequence of length 7

The code causing this error follows

I tried several ways to create the popup. If the sub menu's parent is the popup itself it wont show, if you try to assign a popup as a sub menu I get

Error Code 441
AppendMenu in createMenu failed.
Also interesting is if I add 4 seperator lines to the end of the menu, it won't crash, but looks unprofessional. It seems that the sub menus add a working line to the menu, but not to the structure in some way. Any idea what is wrong and how to fix it.
