text color palette box

It does not seem to work correctly.

I just did a quick test and it is working on my mac.

As usual, when the application somehow misbehaves, one of the first things to try is deleting preferences.

To delete preferences, hold down command and option while starting FCP X and click Delete Preferences.

The application will start in a default state, and open an "Untitled" library.

Reopen the library you were working on, set the preferences the way you like them, and try again.

Hopefully that should help.

Also, I have to clarify my observation about selecting the text. The changes should apply to the whole text if nothing is selected.

If some of the text is selected, only the selected text should be affected. That is how you can have, for example, a word appear in a different color from the rest of the text.

Select the text in the viewer before clicking the color well.

Try creating a new library and a new project, and do a quick test. Same thing?

Try logging in as a different user, and do a quick test. Same thing?

Uninstall Chrome if you have it. Reset your preferences. Close the application. Hold Opt-Cmd has you double click your library to launch the application.
