I haven't had any apps crash when I installed Complx. Both of my phones now are running great. I had issues with root when I put ICS leak on my wife's phone yesterday because something happened to my root, but once I finally got flashed back and redid the process I was GTG. Are you sure it is due to complx and not your root itself?
Yeah I've done fresh fastboot/updates a couple of times. The only apps that seem to have issue that I use are Root Explorer and Sqlite Editor. They both work fine until I flash this then they both start crashing. Root Explorer is usable as it randomly crashes and sqlite editor won't finish loading the databases so it is unusable. Both work fine without these mods installed. If I have time I will poke through this thing and see what he has going on and try to find a fix.
