Session freezes for all connections

Hi

I've just started getting sessions freezing up over the last few days and it's getting to the point where Teamviewer is almost unusable.   

This has been tested from multiple computers on multiple networks to multiple remote computers and I'm seeing it on all of them.

I've had a search through the forums and tried disabling UDP & Video acceleration on both local and remote machines but nothing seems to be helping.   Does anyone have any suggestions and is anyone else having this problem?

Thanks

Ash
