Corel Draw X7 using excessive CPU?

I have been using Corel Draw since X4 and have had a problem start up. I recently upgraded my Windows 10 install with the November 2015 update. I am now finding that when I load a file to work on in CorelDraw, my cpu load for Corel goes up to about a constant 42-45%  and the overall machine load cycles between 75-96% which slows the overall machine down to a crawl. Is anyone else seeing this problem?Why would Corel use so much CPU just sitting there waiting for me. This is happening with a file loaded and I'm not doing anything to it. I'm looking at upgrading my laptop and want to avoid this problem on the new one. Thanks!
