Cursor blinks after enabling Zscaler with Cisco Anyconnect VPN client


We’ve a peculiar behaviour with Cisco Anyconnect VPN client & Zscaler Client Connector.

When we enable Cisco VPN & then activate Zscaler Client connector; cursor keeps blinking making it practically impossible to perform any sort of operation on machine.

We’re running Windows 7 with Zscaler client connector version

Could someone possible guide us in correct direction for the reason of this problem…?
