On our Sage 50 US General Discussion forum, it was brought to our attention by multiple users that after installing Windows 10 build 1903, Sage 50 users have been experiencing issues. This has been addressed by an optional Windows update. A link to this update is available in Sage Knowledgebase article 98667. If after installing this optional update you continue to experience flickering, please follow the remaining option in order to address your performance issues.
You reference Option III, but when I click on this - 98667, it only has 2 Options listed?
Apologies! It appears that the article was recently updated. The optional Windows update is now available under Option 1. I will modify my original post. Thank you!
