Java: Sun1Studio (ME) Windows without text

[Joel Alexandre <jcma@rnl.ist.utl.pt>]

Hi,
i make java aplications for mobile phones.
i used to use jbuilder + mobileset(windows), but i want to leave win for 
good.
So i tried to install some ide (sun1studio).

i installed j2sdk1.4.0:

$ java -version
java version "1.4.0_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_03-b04)
Java HotSpot(TM) Client VM (build 1.4.0_03-b04, mixed mode)

Also installed SunOneStudio, MobileEditon version.

but when i run SunOneStudio i only get windows with no text, as you can see here:

What could be my problem???
i've tried netbeans i the results are the same.

Thanks
Joel
