Will 2.1.4 (v82) work in Leopard?

Hi Gang

I use Super Duper 2.1.4 (v82) in a G5 Single 1.8 that has Tiger 10.4.11 installed.

My other machine is a Dual 1.8 with Leopard installed.

Can I install Super Duper 2.1.4 (v82) in the G5 with Leopard?
(just copy my registered/licensed install file and re-install it in the other machine)

If we're ok (so far), my last question is; As I multi-task with the two G5's, is it possible to use Super Duper to clone a few external drives with the G5 that has Leopard, and then read the contents properly (without glitches or mis-matched data), with the G5 that has Tiger installed in it?

Thanx
Mike
