PL/SQL Developer - question about the Editor preferences

[patrickk]

I am fairly new to PL/SQL Developer (Version 6.0.6.947), so please bear with me.

When I initially began viewing PL/SQL code in the Editor, all commented code displayed in italics and the color red, key words were bolded, etc. For some reason, all code is now displaying in blue, standard print. I clicked on TOOLS -> Preferences -> User Interface/Editor.

Everything in the Syntax Highlighting section appears to be set up to my liking, and the enabled checkbox is checked, so I'm at a loss as to why my preferences aren't displaying in the Editor per my setup. What do I need to do to have the editor display the PL/SQL code according to my setup?

Any help would be greatly appreciated.
