I have recently installed Draftsight. It installs successfully but when in the drawing space the mouse will freeze if it moves across a drawing line. It appears to stick to the line. 

I have previously run the free version of DS on this same laptop. 

I have tried updating the graphics card drivers but it has the latest available version.

The following messages are displayed in the command window after start up:

An unsigned add-in, DSHomeByMe.dll, has been detected, and will not be loaded. Only signed and authenticated add-ins are permitted.

An unsigned add-in, ImageTracer.dll, has been detected, and will not be loaded. Only signed and authenticated add-ins are permitted.

Are these files required?

Has anyone had a similar issue?
