Spline Crashing SW2016

Hello,

I have been working with Solidworks 2016 for a couple of weeks and I encountered a serious problem when drawing splines on a sketch.  I have been roughly tracing the outline of logo on the front plane, and i have found after i start a new spline (in the same sketch) SW decides to crash and gives a notice that it doesn't know what happened.  It usually allows me to draw one spline before it decides to crash on the second spline, so I have to save very often.  It is an annoying issue and I wanted to see if anybody else has had this problem.

Thanks,
