Thanks for noticing, Nikita. It could still be working in Windows XP without being updated, many programs with a firm build will run no probs under many versions of an OS (such as Windows) without any padding - but the only way to find out is to test it. If it needs DOS as a ground it won't run in xp for sure; Windows 2000 was the last to include the old bedrock software of DOS and that helped neck off some older programs when xp arrived (many interactive cd-roms will refuse to run in xp and Vista machines for that reason).
(ten minutes later) I tried downloading it to test in xp, but the file is not available any longer - deleted. Sorry?!
Well, better make another google search for storyboarding freeware software or the like, that's how I found this no longer existent program.
