Phone dialing someone other than you select?

[trip]

I'm using the official HTC Sprint 6.1 ROM and have noticed that sometimes after I am typing a name (on the keypad), selecting it, and hitting the d-pad to dial it dials someone completely different.

I will hit end go back and do it all over and it works fine. I find this really annoying although it happens infrequently but enough to piss me off when i start calling someone totally different than I had in mind.

Anyone else had this trouble? Do anything to resolve it? Thanks.
