problems with manilla 2d

I have just recently installed manilla 2d and I really love the way it looks but when I leave my phone on over night, it is locked up when I go to use it. I have to soft-reset every time. I was wondering if there is a conflict with it and wm6.1 on sprint's htc touch. Also, I was wondering if anyone knows of a good, loud alarm that works properly with manilla 2d. I have been using ageye's g-alarm which worked great until I installed manilla 2d.
