Last night, I went to a webpage on the factory browser that caused my browser to lock up, couldnt hit stop or refersh or even when i typed an address it wouldnt goto the site. I tested skyfire just to be sure i had internet connection, i did. So, i opened Advanced Task manager(dont have it running automatically) and killed the Internet task, as well as killed Advanced Task manager so it would close itself. Went back to the web browser and bam, it was good no rebooting. this also works well when u get those weird text message errors, just close the messaging task and reopen it. Otherwise i dont let task killer run at all.
