Phone freezing after calls.

I am having a problem every now and then after ending a call my phone freezes and I have to do a battery pull. Just wondering if this is isolated or are other people experiencing this. This seems to be the only problem I am experiencing right now. I am really happy with .90 OS.

i haven't heard of this issue before, i monitor these forums throughout the day and this is the first time ive heard of a specific issue like this. the only thing that bothers me about the phone "app" on the storm is that it lags when answering and hanging up.
