DraftSight 2017 x64 SP1: Issues with dimensions and zoom

Recently, had to upgrade from windows 7 to windows 10. downloaded DS 2017 x64 SP1. Immediately, started having 2 issues:

1) When dimensioning, the auto snap will show snapped to and endpoint. However, when I create the dimension, it is not connected to the endpoint and can be several units off. Multiple tries are needed to get it as close, but no truly snapped to the measurement points - what can be done to fix?

2) When zooming, system crashes at random. Typically, crashes once per 5-8 times zooming. I have learned to click save every 90 seconds.

Does the 2017 64 bit have bugs and needs to be upgraded to 2018?
