Thanks for dropping by on the QuickBooks Community page, @RDC DrJ.
To help address your mouse pointer concern, I'd suggest getting in touch with an IT specialist or computer technician. They can assist you in properly configuring the mouse settings on your computer to best suit your needs.
You may also want to review the System Requirements for QuickBooks Online to ensure your computer and internet browser are compatible. Checking these requirements can help optimize your experience when using the product.
Please feel free to post any other QuickBooks-related questions here, and I'm happy to provide some troubleshooting advice. Have a great day!
