Screen not responsive to when I get phone calls

[Beezzy]

When Im in the middle of using an app my and my Evo will get a phone call and then when I try to answer a phone call my screen becomes unresponsive and wont work so the phone just rings and I have to wait till the phone call ends. Does anyone know how this can be fixed or what to do to prevent it?

Mine is doing the same thing. Also, I can't hang up right away, or sometimes answer at all even when not using another app.
