I am designing/drawing images for my web site in version 3.7, but I also have the upgrade to version 4.0 and would like to install and use that version as well, (also, so I can view files made with 4.0 on the same computer). Is it possible to run two versions on the same hard drive (maybe open up Koolmoves version 4.0 to a new folder on my hard drive), or would that cause a conflict? If not, then I'll just install 4.0 on my other computer.
