AS crashing/freezing after trying to copy

Hello E-Learning Heroes,

I'm using Articulate (Update 6) with a Virtual Machine (Windows 7 / host is Ubuntu 14.04) and it worked perfect the last year - until now.

Whenever I try to copy an object (slide or image) Articulate is crashing/freezing but the Virtual Machine is still running. Is there a solution for this problem?

Thank you in advance!
