Right Click on Context Menu Very Slow to Respond

I have uninstalled and reinstalled DO 12.7 in Windows 10PRO on a Dell desktop with ample memory and speed, etc., and whenever I right click on a file to cut, copy, etc. it takes at least 5 seconds before the menu opens to select a command. I do not recall having this problem over the years I have been using DO, but now it has become a real nusiance. Are there any easy fixes to alleviate this issue? As I just reinstalled the program it is basically in the default setup.
