Hello,Mark Bruno1
Thank you for posting in the Microsoft community.
Thank you very much for your detailed description and testing, we will try our best to help you, we accessed the Google Drive link you provided but do not have permission to access the file you shared, please can you turn on the share view permission so that we can further understand your problem.
If it is convenient, please try to connect to another system with that mouse and check if it will double click.
Then exclude any third-party software interference, start cleanly first, and then directly test whether the problem exists. For details, please refer to: How to perform a clean boot in Windows - Microsoft Support
Finally, please follow the instructions below to enter Safe Mode and perform the test, which will detect the problem with a minimum of basic device drivers:
1.Press and hold the power button for 10 seconds to switch off your device.
2.Press the power button again to turn the device on.
3.Immediately after you see Windows start up (e.g., some devices display the manufacturer's logo on reboot), press and hold the Power button for 10 seconds to turn off your device.
4.Press the Power button again to turn the device on.
5.During a Windows reboot, press and hold the Power button for 10 seconds to turn off your device.
6.Press the Power button again to turn the device on.
7.Allow the device to reboot to auto-repair and then select "Advanced Options" to enter winRE.
Once in winRE, on the "Select Options" screen, select " Troubleshooting > Advanced Options" > "Startup Settings" > Reboot". After the device reboots, you will see a list of options. Select "5" from the list or press F5 to enter Safe Mode with Networking. Check if the problem occurs in Safe Mode?
All of the above tests will help us to understand this problem and we are looking forward to your tests.I wish you all the best and please feel free to contact me if you have any questions, I look forward to hearing from you which will determine where we go next!
