Adobe FrameMaker has stopped responding

Had problems with Adobe FrameMaker 7, then 11 for many years now. Each time I start dragging the cursor over a series of paragraphs, or holding the mouse button while selecting tracts too long, it stops responding. I put it down to incompatibility with Windows XP as per Troubleshoot system errors and freezes in FrameMaker 9 (Windows XP) . I also thought it could be my laptop or a corrupted file so installed FM time and again. 

Two weeks ago, I upgraded my laptop to the latest Dell Precision 16 which came loaded with Windows 10. I also upgraded to Adobe FrameMaker 15. And voila.... THE SAME PROBLEM! Adobe FM15 also STOPS RESPONDING even with all these brand new investments. Watching the ever-turning wheel go round and round is very frustrating!!!!

I was about to refer FrameMaker to other colleagues but this puts a stop to that unless maybe someone out there can provide a solution.

Any ideas?
