I'd think it must be coding that causes the color problem, since the color is changing, and that only happens via code. My RTB version is 6.00.8804, so I guess your number was parsed differently. I copied it directly off the file properties dialog. The file date is 5/22/2000. Your number seems to equate to 6.00.8169, which I find is from 6/24/1998. Still, I'd be more than surprized if the version has anything to do with it.

Maybe later I'll put a watch on the color code, and see what shows up.

Unless you got a beter Idea, I'm thinking of checking the File size and adjusting the scrolers multiplier according to the file size... in steps...
That further complicates scrolling. I'd again recommend the Long variable (Currency seems like overkill IMHO). Just set it anytime you set the Max, and use it in place of the property.
