I have killed this instances and can't reproduce it. Before it happens, i moved some files and folders and after i accidentally deleted a folder (ssd and no recycled.bin on) i made a restore with Acronis true image and because the deleted folder blocked, i closed all MC instances with right click in Win10 taskbar. 2 instances kept staying after this actiion, but could be closed with Alt+F4. Then i made the restore and later i have seen that MC always using CPU und detected taht this Processes running. This was no " minimized to task bar" and no "contantly changing so it it rescanning" and no "gettting Icons". It was just a failure i guess. If it can't be reproduced, is my report senseless. sorry.
