Issues Moving Files From/To Folders

The issue is when trying to move a file or group of files from one folder to another, like dragging and dropping files, one of the files will open in its respective application, leading to failure of moving files. At first I suspected the files were set to open with one click, but that's not the case. I've tried going slow, but it seems like when a file's icon is highlighted, even after a long pause, the file will open when clicking on it once more. Some examples would be when organizing photos or documents and moving files into different folders, groups of photos or documents are selected to move and when attempting to drag and drop the files to another location, one of the files will open in photo viewer, or Word or Acrobat. It's very frustrating and I don't recall moving files with previous versions of Windows to be this frustrating. Thank you.

No, copy and pasting are fine.

I will try with new mouse and report back. Thank you.

New mouse seems to have done the trick. Thank you for helping me out.
