Thank you for the reply.
I did verify that both the “Touch Screen Enabled” and “Active on Startup” are checked.
The application is completely touch screen based and all other components (tab strips, buttons, drop downs, text fields, power table click event scripts) work just fine. The only component that stopped working after the upgrade from V7.7.3 to V7.8.0 is the text area component.
Looking at your screen shot of the Project Properties, it looks like you are not testing with V7.8.0. On this version, they added a Scrollbar Width (pixels) entry between the “Touch Screen Enabled” and “Active on Startup” selections.
Anyway, I’m thinking it is a bug for Inductive Automation to look at.
Thank you for your help,
