on screen keyboard problems

[mese79]

Hi
I'v installed fedora 15 on my hp tm2 tablet pc and now i look for the best on screen keyboard application.
I try almost all possibilities, but there is two problems:
1. How could i change authentication window position from modal dialog into normal one?
I mean this window which disables all other windows and applications behind it:


2. Why gnome-shell related key like Super_L or Alt+F1 almost not work?
i.e. in 'input-tab' it works frequently but in 'florence' or 'onboard' it doesn't at all.

Thanks.
