Problem with Meta-Key

[Rick Janda]

Hallo,

I use Lyx 1.1.4.
It seem, that lyx always use the key with modifier bit 1 as Meta,
 independant of the according keysym.

I use a keybord with seperate key for Meta and Alt.
As default, mod1 is assigned to Alt and mod4 is assigned to Meta.
Therefore, Lyx thinks my Alt key would be Meta.

Can I change this behavior without changing my X keymapping.

Thank you, Rick Janda
