Grail

[Ivan Van Laningham]

Hi All--
Since I'm looking for an html widget in Tk, I thought I'd give grail
(grail-0.6) a try.  When I start it up, with whatever URL I give it, I
get the following traceback:

------------end trace-------------------------

Any clues?  I'm running on WinNT 4.0, SP5.  160MB ram, PII 400Mhz.

If this can't be made to run, are there any HTML widgets out there?

Tnx,
Ivan
