One of the weird changes to my computer, due to its recent "illness", was that the repaired unit has a creepy mouse.
Use the optical mouse to put the cursor on an icon or "button", and leave it for a moment, and it begins to creep away. Always toward the upper left. Curious. Maybe the mouse has a hole up there that I never noticed before.
Sometimes it becomes a chase. I put the moving mouse on a button and try to double click before the mouse escapes. Right now it is sort of sporting, but I think I should try to track down the "bug" that my "mouse" has caught before long. The game is afoot at present, but I fear it will become tedious before long.
For now the mouse is creepy
