Source Code Highlighting Lost

Several months ago I lost the source code highlighting, (View: Source Edit).
Many hours of web searching yielded no explanation or way to correct this so
I had to live with it.

Last night the highlighting was back on, for about 15 minutes, then was gone
again. This kind of a tease is unbelievably frustrating.
Would you know what could be causing the colors to disappear and how to
correct it -- permanently.

I have checked the registry and verified that 'Show Source Edit Color' is
enabled. My OS is XP Home, SP2 and Notepad is my default HTML editor.

If this is not the forum for this question please point me to the right one.

Thanks!
Bill
