My Galaxy Indulge was doing the same thing this morning. I rebooted it and all is well. After reading this I cleared my quick launches as I do not use them anyways. I think I slept on my phone last night and that could have caused my issue. The phone said I failed at the design thingy to lock the phone when I woke up so I guess my ass could have also done something to make it use the quick launch. The search key was not stuck or anything. I checked that 1st. Thanks for the thread
