Big bug in frameName with uppercase

[bertrand.lepoittevin@grou]

There is a big bug when using Frames with name containing at least one uppercase letter, like "Main" instead of "main" => error.

Changing :
inside File 'Index.htm' :
<frame name="main" src="frames_body.htm">
with
<frame name="Main" src="frames_body.htm">

and file 'frames_side_array.js' :
,"Languages","show-menu=languages target=main;sourceframe=main",,"#",1
with
,"Languages","show-menu=languages target=Main;sourceframe=Main",,"#",1

it seems that it comes from a unwanted lowercase conversion
inside mmenu.js.

Config :
IE 5.0 or IE 5.5 / Milonik Menu V3.4.0.3 / WinNT
