Numeric colors in MW change under Win2K and XPRandal, when I tested your
same numbers with MW 2.05 and Windows XP, color 103 remained 103 with a
colorunder check; 90 remained 90, etc.  And yet I too ran into this problem
a long time ago.  I remember that a project stopped working until I changed
a certain color to 21.7 (which was *not* the color I had selected from the
palette!).  I really don't remember if I had created the original project on
a Mac or on a PC.  At one point my school switched from Macs to Windows 98
and then to Windows NT.  The problem might have occurred after the switch to
NT.

I'm guessing that if you create a project from scratch now with Windows 2000
or XP, then the colors will remain as you expect them to be.  And I *think*
they'll still function properly if viewed on a Windows 98 machine.  But this
situation certainly concerns me because I've posted many projects online
which would be viewed by users with a wide variety of operating systems.
Every now and then someone writes to tell me that one of my projects doesn't
work, and perhaps this color problem is the reason.

Oh wait!  I think I remember now!  I think it makes a difference if your
machine is set to 256 colors or thousands of colors or millions of colors.
It was when we switched our lab from 256 colors to full color that I had to
alter some of my code which had been developed originally with a 256-color
setting.

Please let us know if this might have been your situation.

  Can anyone explain what is going on with my numeric colors ?

  Using MW 2.05 on a Windows 98 platform I have no problem drawing a
rectangle and filling it with a color and then using colorunder to test for
a color, as in:

  setc 90
  fill
  if colorunder = 90 [do_this]

  However, when I move the code to a Windows 2000 or XP platform, the colors
that I set and the colors reported are often not the same:

  setc 90
  fill
  show colorunder
  80.1

  setc 104
  fill
  show colorunder
  104

  setc 103
  fill
  show colorunder
  102.8

  Some colors stay the same as set, and some change to a different,
fractional number. So far, all fractional numbers appear to be precisely a
decimal tenth, but this is very confusing. It makes it fairly difficult to
use colorunder to test a color, unless you manually verify all the colors
that you have set. Anyone have any ideas?
