Please describe the problem:
I'm using the Scintilla editor.  If I choose a custom color for displaying comments, then my color is ignored: comments appear in black.  Furthermore, any text I select is displayed as an unreadable black rectangle.

Steps to reproduce:
1. View a source file in the Scintilla editor.
2. Choose Settings / Preferences.
3. On the left-hand side of the Preferences dialog, choose Scintilla Editor.
4. Press the Colors & Fonts button.
5. In the "Select highlight style to edit" box, choose Comments.
6. The "Fore color" button will appear red (assuming you have the default coloring scheme).  Click it and choose a different color.
7. Press OK and close the Preferences dialog.


Actual results:
Comments are now displayed in black.  If I select any text, the selection appears as an unreadable black rectangle.

Expected results:
Comments should be displayed in the color I chose.

Does this happen every time?
Yes.

Other information:
This worked until a few days ago, so something must have gotten broken recently.
