Thanks for the reply. I can update it when I get 4.5, but this seems like a different issue — I can no sync at all. Every 10-100 minutes (I do a lot of copy paste), my MacOS clipboard stops updating when I switch from NX session to Mac. One work-around I found is to try to copy/paste something from my MacOS client into NX session. After that the clipboard gets “unstuck” and I can do it again.
