Boy! That was quick!
Unfortunately I'm having problems locating Tk::Zinc. It's not showing on PPM under ActivePerl, and CPAN Tk::Zinc doesn;t appear to find it either. The CPAN website lists http://www.tkzinc.org/ or http://freshmeat.net/projects/zincisnotcanvas/ as possible sources, but the first looks duff to me, and downloading from the second reports 'file not found'.
Anyone know where I can find Tk::Zinc, please?
