BB Tour 9630 :: Frozen After Typing (correct) Password

Any ideas before I do a hard reset?As of last night, my Blackberry isn't fully unlocking after I type my password. I type the correct password and hit enter, the password entry section turns dark (or it will stay on the "Enter Password screen" and appear to freeze). (If I type the wrong password it simply prompts me again, so i know I am typing the correct password). This is after multiple battery pulls.Sometimes after typing the correct password, I can hold down the blackberry button and it will bring up the box that lets me switch to BBM, the browser, the Home Screen, etc and I can "switch" to that program, but there is a sort of frozen shadow of the Enter Password box over what ever app I switch to and I can't use the trackball or keyboard in those apps.This "frozen box' is preventing me from using any application on my BB!I CAN receive calls. Barely. I can only make calls if I pull battery and DON'T unlock the phone and go to the Place Call option.I upgraded to OS 5 over a week ago and things were fine until last night. I can hear my BB when it receives messages (the tones work) or txt etc but can't read anything due to the lock up!The only suspect is Google Talk which I installed two days ago and seemed to be hogging resources and draining the battery, however the phone worked fine for about a day with it on. Perhaps Google Talk is launching at startup and hanging things up? I doubt it but this is full disclosure.I have also, pulled battery and removed the micro-sd card to see if that had any affect -- alas to no avail.One analogy I can think of is it as if the Windows Explorer is hung but everything else is working.
