Teamviewer hangs with "Pasting from ..." Message on host

[DHKaplan]

I'm using Teamviewer 12.0.78517 on two OS X 10.12.5 machines. Periodically my host machine will have a notification "Pasting from " followed by the client computer name. This brings up the dreaded OS X "beachball" and both systems hang for a minute or two. What is this? How do I fix it? Thanks

I too have the same problem. It is incredibly annoying and it blocks my (remote) computer for quite some time and in all other running applications.

Are we two the only ones having this problem?

Help!
