"Activity Messaging (in application Messaging) is not responding" Force Close or Wait

[blackcracka]

You have to keep your message counts low or the phone will freeze at the moment.

This is the BEST answer it worked for me exactly like you said! Thanks A MILLION!!

Yeah, the more messages the longer the wait -- and if it exceeds a threshold then you'll get that pop up.

So, every few weeks make sure you clean out all your length text message threads. I'm surprised the settings don't have an auto delete feature built in like most phones. App idea?

SOLUTION: you have to delete the long threads so the you stopp seein tha msg...thas what i jus did and i no longer see that stupid anoyin message

I get this message ONLY when deleting threads from my Hero. I tend to hit force close because waiting takes forever.
