I am having a strange problem. Whenever I try to copy a group of entities I get an error message that reads "Cannot copy entities to clipboard."

I am encountering this on both my linux computer running the latest version of Linux Mint and Draftsight 2016 SP1. I am also encountering the same problem on my windows computer running Windows 10 and Draftsight 2016 SP1.

It appears to be limited to files created in older versions of Draftsight. I have no problem with anything I created in Draftsight 2016.

Saving them as blocks does not work either.

Any suggestions to resolve this would be appreciated.

Thanks
