Tom:
I'm pleased that you found it useful!

Sivakatirswami:
One way to make sure all the text is set back to the default color  
might be to:

      lock screen -- hide the following selection process
      select text of tSpellField -- your field name here	
      set the foregroundColor of the selectedChunk to empty -- return  
all text to its native color

Of course this assumes that your field doesn't contain any odd pieces  
of text that are *supposed* to be colored differently.
