Displaying some spelling dialogs while spell check highlighting is in effect unexpectedly changes many words from their proper color to reverse style text (all the same color).

To reproduce:

- toggle on spell check highlighting
- select either of the two Spell Check dialog boxes (Language... or Options...)
- press any button (Cancel will do)
- colors are now confused.

Toggling syntax highlighting off/on (or on/off if it was initially off) returns all text to correct colors.
