Norton identity safe toolbar does not respond on some IE tabs

Hello

 

I am using Norton 360 premier 20.2.0.19 and IE 9 32 bit

 

Sometimes I find that the identity safe toolbar is unresponsive on one or more IE9 tabs and responsive on others

 

I am using a local vault

 

Also I am getting quite a few IE9 crashes likewise system does not always shut down and has to be powered off  - not sure if related

 

This has started recently - last few days

 

Any ideas welcome

 

Martin
