eeek! i never had any intention of using the hd with more than one machine at a time. my thinking is that i would be able to use it on my home desktop computer much of the time and then transfer it and use it on my wife's laptop (and eventually mine -- Ti-book 2) when i take it out to do video work away from home. i thought if i could install the software on a bootable external hd (os 9.1) then i wouldn't be breaking the law and installing 1 purchased software package on more than one computer (wouldn't look good for someone in my position teaching people about computer ethics, etc. to not be so ethical myself). sounds like it might be a little iffy after all.<br><br>[color:blue] -sean</font color=blue>
