Problem - "USSD code running" while answering calls

[Guest filipedua]

Hi mates

I'm facing an annoying problem and I'm here to consult you guys and hope you can help me.

Sometimes I'm not able to answer incoming calls, while the phone is ringing it displays a message box saying "USSD code running" and because this box is shown in first plan, I can't slide or press any button. After reboot the phone all starts working fine.

I'm running GR4 (Stock LG Style), BB 725, Kernel 2.6.32.9

I don't think I have any app that could cause this but anyway here is my app list:

-Torch

-eBuddy

-Shazam

-GetRIL

-Antek app Manager

-2x Client

-ES Explorer

-Convert Pad

-Facebook

-RockPlayer

Thanks in advance for any help solving this issue, and thank you Paul for all the effort supplying us with great roms.
