Keep this in mind. When using ADW EX on the stable CM7.0.3 and when using it on stock stable LG firmware, the software works fantastically and I don't have any problems.
I have the LG Optimus M which is a MetroPCS version of the Optimus One. CM7 does not officially support the Optimus M, and the firmware we have for it is a ported version from another Optimus phone. I have no idea if the original CM7 build I have for my Optimus is "stable" or not. LG also just recently released the source code for my version of the Optimus M (2.2.1 rather than 2.2) and a fresh OC kernel has only been available for a week or two. This kernel let me run fairly stable at 787 MHz which is the average it seems for this phone, but I was left with a random crash, sometimes several times an hour, that would hard lock the phone and necessitate a cold boot. I couldn't figure it out so I flashed back to stock last weekend and have been running trouble-free 'till today. I figured it was a problem with the kernel.
Cue Nook Color. I had it set up software-wise exactly like my phone at first. Running stable CM7, everything was perfect. I wanted to OC though, so I started playing around. Once I sorted out the boot issues with the OC kernel (that you helped me with) it was running fantastic as well at 1.2G. It wasn't until I had reinstalled everything and set ADW EX as my default home that things started to act up; that didn't happen 'till way late in the day after work. I thought it was just a random OC-related crash at first, until it started crashing randomly on the stock clocks, too, exactly like my Optimus.
That's when I realized it must be a common item between the two, since the behaviour was identical. After a few hours of trial and error, I narrowed it down to those two softwares I mentioned.
I ran all night and all early morning perfectly without that software. As soon as ADW EX was reinstalled and set to home, the problem came right back. I took it off and am using the included free ADW and it hasn't been an issue.
I have also since re-flashed my Optimus this morning with CM7 and the OC kernel, and it's been singing along all morning at 787 MHz with no ADW EX.
