problem on mini screen display

[googooroom]

i know it is kinda weird.
i have the latest 2.1 OS in my mini x10
recently, i have rooted the phone and try to install JIT
upon finished the JIT installation, the phone reboot..
then the whole screen go haywire.
the icons becomes very big and the home screen cannot display all the widgets or rather all widgets packed together.
something like windows when you send the resolution to high but the display on the monitor is low.

any expert here got any idea? how to restore it to normal display mode?
the mini x10 is on ADW.launcher

thanks

I would have to advise reflashing it and perhaps not installing JIT this time
