Hi KR Roach ,

Thank you for reaching out are you still experiencing this issue? Here are a few general troubleshooting steps that might help resolve your mouse scrolling issue in Sage 50:

1. Restart Your Computer: Sometimes, simple issues can be resolved by restarting your computer, if you haven't tried this already.

2. Run Sage 50 as Administrator: Right-click on the Sage 50 shortcut and select "Run as administrator". This can sometimes resolve issues related to software permissions.

For broader issues not directly related to mouse scrolling but that might impact Sage 50's responsiveness, you can refer to the article "Error: 'Sage 50 has stopped responding' or program is not responding when opening". This article provides a comprehensive approach to troubleshooting various issues that might indirectly affect how peripherals, like mice, work with Sage 50. Hope this helps!

Warm Regards,
Erzsi
