Fix the forms functions (combo boxes etc.) that were broken in the upgrade from version 17 to 18.
In the upgrade from version 16.17 to version 16.18 of Excel, the operations available under the Developer tab were broken. The setup of operations like "Combo Box" works, but the process will not execute. This is a capability in Excel that I use literally every second day. I have solved my problem by downgrading to version 16.17, but anxiously await a patch that will restore their functionality.
