FASTERTHANU  for me on 10.6.1 (64) toggle button is buggy : show invisibles files ok but to come back to the original state impossible and finder stuck a 100% of cpu.

i same time i've tried the invisible button : do nothing.

i've sent an email to the dev but still no answer.

so for me : toolbar is not really optimised for snow leopard and the dev are not very reactive

thanks to help me if u have answers
