My Treo has been locking up a few times and I think I have narrowed it down to Voice Dial form PalmOne.

What would happen is my palm screen would be off, but the Treo on (waiting for a call) I would get a SMS or at times a call and the LED would go solid GREEN.
I would go and try to power on the screen and it would not go on no matter what I would do.
I would be forced to soft reset my Treo 650 (GSM)

I have removed VoiceDial and so far (12 hours) I dont have this problem any longer.
Anyone else have this issue with?
And does anyone have a good alternative to Voice Dial?

I liked it because you did not have to teach it or train it.
And it not only called up and dialed a contact but it also opened apps upon request.
