I am very disappointed.

I install 2015 release and it was impossible to use on yosemite. It was buggy on cursor and snaps.

Now the release 2015 SP1 solve the problem with the snaps but mouse cursor, zoom, pan window selection and any other video function are slow and annoying...

Draftsight was the best 2d CAD for mac on the market till this terrible version...when are you going to solve the problem or republish the previous version so we can keep on working till you'll solve the problem???
