netbeans mobile emulator: change screen size

[Chameleon]

I work on netbeans 5 b2.

Is it possible to change the width and height of mobile emulator's screen?

My mobile has a 128 x 128 (+/-) screen.

netbeans mobile emulator has a (maybe) 320 x 240 screen.

So, everything is fine for netbeans emulator but when I upload to my
mobile is too large.

I tried <click on project> -> properties -> abilities ->

ScreenHeight = 128
ScreenWidth = 128

but nothing.

So, it is fixed 320 x 200?

Thanks
