BT Build 500 Question

[mp1]

I am running a custom ROM which has the BT Build 500 that has been working flawlessly on so many ROMs since the US Cellular and VZ 6.5 ROM releases.

I am having problems hanging up when a data connection is active before an outgoing/incoming call.

When data is active, it fails to hangup initially, then disconnects after a 5-10 second delay, and displays the error "Cannot Connect, Dialed #777, Cannot connect for an unknown reason".

Does anyone know how to fix this? I do prefer this ROM and would like it working on THIS ROM so please don't just suggest I switch to another Chef.

Thanks

I have also already tried applying the Reg edits from this post already.
