9700 Freezing Far Too Often

I've just become accustomed to using the Blackberry group chat thing with people abroad. And with using this new (to me) feature, my blackberry has suddenly slowed down. The little square clock has popped up on numerous occasions while when I am actually in the Blackberry Messenger app my entire screen freezes up. Within five minutes I've had to reboot twice! I believe that to be ludicrous.

Before using the group feature my normal bbm messages would take a few minutes to send or even acknowledge that they are being sent, but now even my typing is ridiculously slow and rather lagged.

I've never known anything about the software or the mechanisms which make a Blackberry work, so I am completely stumped.

Help?

Try deleting/reinstalling the application. Or re-loading the operating system.
