Handcent is much better anyway buy i got stock with no issues. If its only when using chomp the delete and go stock for a few days and see what happens. Also i had this issue when i had a task killer on my phone. Deleted and now no reboots.
I've had the DX since 7/16...ordered online. I have as a couple of reboots/freezes since then. Called Verizon and they had me do a factory reset. I have slowly reinstalled all apps...No problems since then. I have gotten in the habit of powering down / restarting in the morning after the alarm goes off. I was thinking the random reboots might be a low memory issue. I wish there was an option to power off at night and auto start at a preset time.
Some folks running ATK have reported funky stuff and then were pleased once it was removed. I know the app has the ability to run well, but it wouldn't surprise me if more and more conflicts don't arise as newer more sophisticated devices hit the market. ATK trying to shut stuff down and Moto trying to start stuff up...then, kaboom!
Not sure what method you used to root but I used easy root unrooted and it made no difference after looking on android central I don't think it has anything to do with the fact that we rooted I've seen other people post the same issue and have gotten replacements with the issue solved
