Ok, out of the blue my computer won't drag and drop anymore. I have searched for a solution in multiple places, but all I can find is the "press and hold the left mouse button and hit escape" or right mouse button or in one case hit escape and control and then release and this doesn't work for me. I've tried it repeatedly both right clicking and left clicking and no luck.
I can drag a window around my screen with no problems. I can press and drag to select a block of text for copy/paste with no problems. I can NOT drag a file or folder or even a desktop icon, either within a window or from one window to another. It will select, but not drag. Also, those headings at the top of a window that denote columns of info (name, date modified, type, etc) where you can put the pointer on the line that separates them to drag the right side over to make a section bigger - it won't drag those over anymore either now.
I have run sfc /scannow and it found no problems. I have run various antivirus and anti malware programs and also found nothing. The computer has been rebooted many times since this problem started, so that didn't help either. I have checked in the registry and the Drag height and width are still set to the default 4. I'm out of ideas! Does anybody have any idea how to fix this problem? I use drag and drop extensively, so this is being a major pain in the behind!
