Thank you for the fast response. I have tried what was suggested in the topic you've linked in your post. However, neither of the two solutions fixed it.

Things I've tried and did NOT fix the issue:

• Running NemProjectPilot10.exe as admin.
  

• Right clicking the "NemProjectPilot10.exe", going into "Properties" and under "Compatibility tab" checking the tick box "Disable full screen optimization"
  

• Running Allplan 2020 as admin.
  

• Trying to copy files in Project pilot launched within Allplan and as a separate client.
  

• Fully updating Allplan
  

If someone who is more versed in German language can find something I've missed in the linked topic above, I would be most grateful.

I have contacted local Allplan support representative in my country but it's been a week already and I've not received a replay. Hence, why I started a topic on these boards.

I have disabled all antivirus softwear (including Windows defender etc...)

I've noticed that every time I attempt to copy within Project pilot, the screen blinks for a fraction of a second, however nothing happens.

Nothing really comes to mind, they are all different workstations (different specs, manufacturers). They are also used by different people who set them up according to their own preferences. Only thing that might be considered as the same is that we all use Windows 10 professional as OS.

I am working with admin account.

Nothing to my knowledge, I guess chance of that happening on 3 different workstations is improbable.

I haven't changed anything after installation has been complete in regard to that, but if you could tell me how to check that in registry I will double check that as well.

Thanks again mate, I appreciate the help.
