Phone automatically dials last call?!

[Scrios]

Has anybody heard of this? My new (to me) Verizon XV6700 has started turning itself on, opening the Phone app, and dialing the contact under "Last Call". I'm running the latest Clean and Simple 3.5 AKU, but it also does this with the default Verizon one.

I've made some common registry and EPST (##77 tweaks, and it's just started doing this. It's lead to some confused voicemails in return, that's for sure.

I've done some searching but found nothing...any suggestions would be great.
