Cool fix ill try it out soon
No BeeJive itself does not do this. It's just when I use it and SMS/MMS or Email together does this happen.
Even alone the SMS/MMS and Email often "sticks" the titlebar and causes the phone to become laggy and then the hardkeys (such as OK, Calendar, Windows Sign Button, and Messaging app hardkey) all become unresponsive and only X-ing out the program is the way to get out of it.
So yeah i think it's narrowed down to the SMS/MMS and Email slowing everything down causing it to freeze.
Sadly it is what i use most
