Mouse Pointer Changes to Pen Arbitrarily

Have a designer that is using SolidWorks 14 SP4. Fresh install and graphics card is an approved card with driver provided from SolidWorks.

The mouse point is arbitrarily changing from pointer to a pen cursor. Moving mouse around and clicking left button sometimes gets the point to change back to pointer but usually it changes back to pen shortly thereafter.

Any suggestions appreciated.
