Okay so you are working away day after day and every now and then when you right click on a folder or file all your Finder windows just up and disappear.
Oh that’s a bother but never-mind it will be back in a minute…… or two.
Basically its the contextual menu folder that has an issue and more specifically the StuffItCM.plugin (from stuffit & co).
Simple solution is to :
Go to “~/Library/Contextual Menu Items” or “/Macintosh_HD/Library/Contextual Menu Items” and delete the file StuffItCM.plugin.
Maybe a reboot or logout/login just to be safe and also empty your trash for good!
Let me know if this works for you with a quick thanks.
I found this out from the thread here.
