Had this happen before and do not remember the cure. I have a text field in a form. I center the title and assign it a color. Center the field and assign it a color. When I run, the title is centered, no color, field is not centered, no color. Regardless of display choices, it pretty much ignores me. What does that?
I sometimes have to refresh the page using Ctrl+F5 to show changes that I have made to colours and other things that use CSS.
Tried a cache cleaner. Closed the program. Rebooted the computer. The only thing that finally worked is I changed the type to integer and the formatting appeared. Changed it back to text and it stayed.
SC is notoriously bad when changing a field format. I have never managed to have it respond immediately. Cache clearing works sometimes, but usually I just wait until I have run a few other apps then go back to it and it may change. Its frustrating.
