What version of MC?
What version of the OS?
Try turning off auto import. Tools > Import
Jim, it is 23.0.74 I downloaded a version a few months ago and I had the same problem with that one.
I had a play about,,,, If I start it up and rush to: Tools> Import>Import a single folder and untick the Audio, Image and Video boxes and hit finish before it gets shutting down the program will run fine,,,, until the next time I go to start it. The three boxes are ticked automatically and I can't find any way to shut them off!
Then again should I have to shut them off?
Thanks, Ray
