RH 6 - Unable to copy/paste

Since 6 beta to now the latest release, it has been issues of slow copy/paste (takes about 30s to execute the command).
And sometimes it results to this “commend not implemented”.

Issue would be resolved if quit and restart the application but happens very often.

Can be a GPU limitation?
If this bug pops up very often, consider making a good bug report. Making a good bug report is important. For that, try to isolate it so that developers can reproduce it. For example: do this happens when other Rhino is open?

Thanks!
The issue seem only to happen when the file has been opened and worked on for awhile (a day or so).
And the app does not actually crush, I have to manually quit the app and restart it to have it function properly. Is there anyway to generate the report without having it crash?
