WDE Makes Mouse Clicks While Accessing The Disk

Hello,

Recently, I installed Windows 10 on my notebook and encrypted the OS disk and external data disk (USB) by Symantec Encryption Desktop. 

Problem
Encryption Desktop performs multiple mouse clicks per second while accessing (read/write) the disks. Particularly troublesome is it while huge read/write operations like encrytping the disk, backup and file copy. It is impossible to work because the mouse continously clicks the left mous button. Thus I loose focus of my document.

The problem happens only while disk operation on encrypted disks.

Technical Data:
Product: Symantec Encryption Desktop 10.3.2
Operation System: Windows 10 Enterprise

Have a solution to stop the mouse clicks while disk operation on WDE drives?

Kind Regards
J
