Thank You for your answer, that would certainly explain my problem.
I have one more question. Yous said that Nokia 7650 will only run on MIDP 1.4... Do yuo know if the software for 7650 can be updated to MIDP 2.0 someday in the future. I mean the first version for 7650 was probably supported for MIDP 1.0... so is it safe to asume that you can update it to 2.0??
Or should I just rewrite the code so it will run against MIDP 1.0?
