DisplayLinkUserAgent Application starts and stops
 

I have whats seems to be the usual problem with occasional mouse freezes. Very annoying.

When I look into the Task Manager I can see that I have multiple entries of DinsplayLinkUserAgent Application where one comes up and disapear rougly once per second. Doesn't seems normal to me. CAn this cause the mouse freezing I see?

Perhaps... could you post the logs from your system then we can see what the software is doing:
