I think its really good to have this programmer now included with WinAVR. Now 
you really do only need a single package to get going, good work guys!

However I too have been getting this verify error sometimes, not always but 
sometimes. It seems to have problems and that it is fine for quite some time. 
Before I started to type this email I retried it to capture the screen output 
but it was fine for a few runs and then failed about 3 times in a row and then 
was good for another 6 or so times. The addresses are not always in the same 
place, they seem to change. I'm pretty sure my hardware is ok as I can use 
PonyProg2000 2.05a for some time with no verify problems. See screen output 
below

I would like to be able to use this, but because its not 100% reliable I am 
still using PonyProg called from my make file with a *.e2s file.

My board is a Dontronics DT006, programmed via the parallel port and I'm 
running on Win2K.

Also I am running avrdude from within the JFE (Jen's File Editor) and when it 
captures the output window, the updating numbers cause it to scroll. Running 
from the CMD.EXE window is fine of course. Would it be possible to have an 
option to print a "." for each block across the screen a bit like FTP, rather 
than the numbers to reduce the scrolling?
 
Any suggestions?

Cheers
