I am running COMSOL Multiphysics on Windows, and when trying to change the value in the Expression cell in one of my tables, the value is not updated.This issue in the Expression cells of all tables where there is auto-complete functionality enabled, such as Parameters, Variables, Derived Values, and Export nodes.
For Windows 10 it started appearing in version 1803. For Windows 7 it started appearing after installing Windows Update KB 4340556.
It manifests itself like this:
- Go to the Expression field in your table, and change the value written there.
- Leave the Expression field by either clicking with the mouse, or using the
Tabbutton on your keyboard.
- The value reverts back to what it previously said.
