Patrick - I was testing some code and had the formal_white theme selected. I received an errorbox message and could not see the text (see attached screenshots). It looks like the color is coming from the parent theme (i.e. standard) and for errorbox the color is #ffffff. I think it should probably be #000000 so that you can actually see the message. I am attaching a patch file and a screenshot with the applied fix for your evaluation. Let me know if you have any questions or need anything else. Peace - Anthony
