PhotoShop CS5 trial downloaded and installed.
Wow, startup and file open are lightning fast!
My system has 18GB of RAM and the PhotoShop performance Preference allows me to set memory up to 17588 MB.
As has been mentioned else-where, it is no longer possible to select "No Colour Management" in the PhotoShop print dialogues. I wonder if there is a work-around...
I am interested in 64 bit as well as accuracy with old Epson SP 9600 printer.
