Not sure if this is resolved after all this time but I would say the answer is no.
I would also question the use of changing the cursor.
The problem can occur in countless situations. Often Windows is looking for an unresolved path or even something like crosslinked files can lock the mouse.
Has it always happened or did it start after something you did ?
Try and replicate the error in safe mode. If you can't, the problem is probably down to an incorrect driver, corrupt or broken software installation etc.
You can then try a selective startup. Deselect all the programs and, one by one, set them to run on startup.
Its a long-winded approach but can bring results.
Other possible causes are damaged hard drive sectors, failing or poorly seated Ram and even general overheating of the system.
