You could have a look at my ProgressBar code and see
how it is done there:

In your, code (http://www.dfanning.com/programs/progressbar__define.pro),
I obtain compilation errord at lines 575 and 634.
Both errors concern:
IF self.fast THEN TVLCT, FSC_Color(self.color, /Triple), self.colorindex
^
TVLCT, FSC_Color(self.color, /Triple), self.colorindex
^
What can it be ?
Thank you,
Francois.
