cannot answer calls when activesync connected

[DomSim]

Hello, i have seen a few other threads mentioning this problem with no working solution for me. I have a sprint HTC touch pro on JD's rom 7.1 and when ever i am connected through activesync to my computer i cannot answer any calls. it rings, all be it, with a long long delay and then the call id pops up with the answer, hang up, or ignore with text options. i can hit answer or hang up but neither does anything. it just stays on this screen with the phone ringins. if i disconnect from activesync every thing works as it should. from what i can tell, i cannot answer the phone because the data session is active and not being dropped for the phone call *** it should. i tried the ##ddtm# switched option that was mentioned, deleted my microsoft exchange setup, and had it stop syncing email all together but the problem still persists. any help or advice?
