Default Notification bar won't pull down anymore

Hi,
I don't know what to try to fix the problem, for no apparent reason my notification bar won't pull down anymore, I tried to wipe everything and reflash 2 differents rom but nothing worked, the notification bar is stuck. everything else on the phone works great.. I don't understand what can cause this..

I also tried a g-sensor calibration with no result.

Maybe its important to mention that when i am in landscape mode ( with an apps ) the notification bar works perfectly fine, but the moment im back in portrait mode, it become impossible to pull down the notification bar

If anyone have idea how to solve the problem please let me know.

Thank you very much

ps. I work hard to learn a language, so sorry for my english.
