[avr-gcc-list] OT: STK500 programming slowdown?

Somewhat off-topic, but you guys seem very experienced at this stuff, so
I'll ask anyway. :)

Has anyone encountered a problem with their STK-500 that causes the
programming process (either via AVR Studio or the command-line stk500
utility) to slow down by a factor of 4 or 5X?

The other day, I accidentally shorted the V+ supply on one of the 10-pin
headers to ground.  Afterwards, the STK500 still works fine but programming
is excruciatingly slow.  It's as if the board is no longer capable of
whatever high-speed serial communication it normally uses for programming,
but is falling back to something like 1200 baud.  Anyone know what type of
failure would cause this?

This slowdown effect is happening with both the STK501 daughterboard and an
external ATmega128 part connected via the 10-pin ISP header on the board.
