I am using the latest verision of thurderbird on a windows 8.1 laptop. I launch thurderbird and then it freezes?

Thanks Wayne. Starting Thurderbird in safe mode worked. However is different in starting in safe mode vs reg mode? Thanks.

Please disable acceleration at tools, options, advanced, general and restart

Better?
