Question Strange and annoying problem when dragging files, pictures and videos with the mouse ?

[aor999]

Often, when I dragging files, pictures, videos and even shortcuts, this is what happens:

What you see me doing is dragging files with the mouse pointer. After a while, the file disappears from the mouse pointer. This prevents me from dragging videos to upload to Youtube and from dragging pictures to websites for uploading.
Why?

try a different mouse, maybe the button of the mouse is faulty

The mouse is relatively new Microsoft Basic Optical Mouse 2.0.
Don't expecting it to have problematic left button.
