I need a program to draw rois on images. cw_defroi doesn't work properly
with ture colr displays (it doesn't properly show the contour while you're
drawing it). Does anyone have a module for drawing rois that works on 24
bit color displays?

I've only ever used CW_DEFROI a couple of times,
mostly because--like you--I find the interface
clunky and difficult to work with. I much prefer
to add ROI capability to my own draw widgets.
The bottom line, I think, is that because CW_DEFROI
employs it's own event loop, there is no way to
get it to do what you want it to do without
modifying it rather significantly. (Actually,
it was my attempt to get it to fit into *my*
application window, as a compound widgets are
suppose to do, that finally convinced me to give
up on it.)
If you decided to add your own ROI capability
to your windows, here are a couple of articles
that explain at least one way to do it:
