i have a treo 600 GSM. I installed a language enabler to Arabic. However, after that i was unable to access the on-screen keyboard (menu/ Edit/ Keyboard). I dont remember using it before i installed the software, so i am not sure if the arabic software is the issue.

At any case, i uninstalled the Arabization software, and it still is the same. When i choose KEYBOARD, i get an error sound.
