iChat crashes and takes forever

My iChat has recently been 'disconnecting unexpectedly'. Not only that, but when I try to transfer files via my Bonjour, it takes FOREVER to start the transfer and the same applies when receiving files via Bonjour. I do have a Jabber account on there as well through gmail. I've had this configuration for about 3 years now and just in the past month or so it has started doing this.

Anyone else? Suggestion?

my ichat crashes also

Whenever i try to do a video chat, my ichat crashes, video cat works fine with skype though
