You won't get much sympathy from me as I don't use Tk at all. I found Tk drifting away from my life when I became a web programmer. Personally, I also find Perl/Tk to be very un-Perlish and more of your standard "create a bunch of objects and pack them up." However, i really would hate to see Perl/Tk die out, but as long as one person out there takes care of this project it won't be abandoned. Are you busy, ATM? :)
