Parallel programming of Tiny26 on an STK500

Has anyone successfully programmed (or at least erased) a tiny26 using the STK in high
voltage programming mode?

I built the special cables needed, but it refuses to work.  I am kind of thinking maybe
it simply doesn't work...  Serial programming works great until I enable PB7 - whereupon
the only way to get the chip back is by a full erase and it ain't working!

Fie.

I am using studio 3.56 and the STK500 software that came with Studio 4 and supports the
tiny26.
