Thanks! That's a very cool little program. I'll have to try out all
the options, but I still seem to have the same problem - if I want
each mouse drag of one pixel to be one step, the slider size specified
with "XSIZE" isn't large enough. For example, in this call to
descrete_slider,

Slider = DISCRETE_SLIDER(tlbID,/DRAG,/step, increment = 1, MIN = 1,
MAX = 400, XSIZE = 400)

the slider will skip a bunch of values (6, 17, 28, etc).

In thinking about this for a while, I have come up with two solutions
1) Just make the XSize larger than I need (37 pixels for my machine -
maybe more for windows (?)). Then I could use the descrete_slider
program.
2) Somehow find out how much larger the slider needs to be by creating
a slider and using tlb_get_size, then resizing the slider
appropriately. This should work, but I can't seem to figure it out.

What I'm worried about is that the sliders may have different sizes on
different machines, not just on different platforms, which is why #2
would be better. #1 would be a lot easier though!
