Can't prevent OMSA Version 8.3.0, session timeout

Since upgrading to OMSA Version 8.3.0, Session Timeout Disabled isn't working and the session always logs out after a period of time. It's running in IE11 on Windows Server 2008 R2 SP1 64bit.

I've tried reinstalling OMSM but that hasn't resolved the issue.

I'm also experiencing the same issue on other machines.

Please does anyone know how I can resolve this?

Thanks,

Simon
