Freezing picture

I am using Yahoo Messenger with Windows Vista. I have a dsl line and can connect with my daughter on a cable connection. We talk for about 45 sec. and then the picture freezes. We both have cleared Yahoo through our firewall. My computer often says Program is not responding. Shutting down. Do you want to send a report? What am I doing wrong? We keep freezing and being cut off.
Please help. Any suggestions will be welcome.

 

Something's crashing but who knows? An alternate is to try Skype and see if that works better.

 

Have you tried uninstalling and reinstalling Yahoo?
