Mac version 2015 (osx 10.7.5) Original install worked but had a few issues like Esnaps not working correctly and it often froze if I had more than one file open and closed one of them.  So I removed DS and downloaded it again and reinstalled.

Now it is terrifically slow.  Simple commands like Line take 5-10 seconds ….. What is going on?  Please can I have the old version back?  V1R5.1.
