Mouse cannot drag-n-drop

Somehow, some funny problem cropped up in one of my clients' PC. The mouse refuse to drag and drop a file from one window to another window. All single (left) click and double click works fine. Even the Windows ClickLock failed to function.

After Google for solutions, I came upon the posting at www.tek-tips.com/faqs.cfm?pid=779&fid=5242 and this is the registry fix you can run to fix the problem.
