tkinter blues (greens, reds, ...)

[Sean McIlroy]

hi all

i recently wrote a script that implements a puzzle. the interface
mostly consists of a bunch of colored disks on a tkinter canvas. the
problem is that the disks change their colors in ways other than the
way they're supposed to. it certainly isn't just a bug in my script,
since i can sometimes change the color of certain disks just by taking
focus off of the window and then bringing it back again! does this
sound like some known bug in tkinter? and if so, is there a recommended
way of working around it? if it matters, i'm using python 2.3 under
windows 95. any advice will be much appreciated.

peace
