Hi Sy Mo,

Hope you won't find this a silly question, but have you tried to unplug the mouse and plug it in again? this might reset the mouse hardware and hopefully it will get recognized as new hardware installation. Also, you might want to check your other software updates, make sure everything is updated in your operating system. 

Let me know how it goes! 

Have a great day!

Hi Oana,

Thanks a lot. As often with so-called silly question, yours was very clever. I had not thought my problem could be hardware-related. Yet, I'm working with my mouse connected in another way today and my cursor is where it should be.

Thanks again.

I wish you a lovely day.

I am having this same problem and tried unplugging the mouse with no success. It was working fine yesterday. I'm using the latest version of Studio.
