Same problem here, only one of our PC have the problem (my W10 PC).
The problem appeared with 6.0.3 to 6.0.4 upgrade, and is still present after 6.0.5 upgrade and full uninstall (FC Tools) and reinstall. As 5 other PCs didn't show the same problem, the opened ticket has been closed after many investigations, and the conclusion that this is specific to my Windows :(
Yesterday, upgrade of a Windows 2016 server from 6.0.3 to 6.0.5 leads to the same problem.
So for me, the problem is still here and I will have to reopen a ticket...
