Default Paranoid android v3.99 apps crashing

Hi. I am running pa v3.99. Whenever i am browsing thru xda, it crashes. Or when i am typing etc. I googled and found no similar cases. If i have to do a factory reset, i might wanna try cm 10.2. As u all say, try them myself and see which suits me. I have been trying pa for a week. So if the only solution is to factory reset. I might just flash to cm 10.2.
