Hi everybody

I'm new !and english is not my native language !! sorry !

I try to program attiny85 with the arduino isp sketch
it's work fine when i connect the pin 13,12,11,10 on the arduino and the attiny
i make a small board with my attiny and a isp connector
but when i connect my arduino isp connector to attinyboard isp connector ; i cant upload sketch.
If i disconnect the pin "reset" on the isp connector and connect it to pin 10 on arduino all works fine ?!!

anybody have an idea of the problem please

i test with ide 0023 ; 1.01
i'm with windows 7

thanks
