right-click menu

I have a folder in my start menu labeled Drives, so I can easily access all of my drives. I had been able to open any folder in any drive using right-mouse click and selecting OPEN. Somehow in the last two and a half weeks (I was down in Lousiania for two weeks) when I select OPEN a “MOVE FOLDER” window opens and I have to click cancel twice to get the folder to open. Searching google has not brought me to any remedy. Anyone have any idea why this has occurred? Thanks in advance.
