well it just has a warning message saying it's for people who have purchased said product before - but it's the internet & they are a bunch of waldos if they think people will actually bother heeding the message.
it reminds me of a daw (digital audio workstation) called Reaper which when you download has an unlimited trial (which is fully functional like the freeware version of Visionaire Studio) - older versions used to come with a funny splash screen on application start-up which said something like: "Please consider purchasing Reaper for x dollars or you will just have to put up with this splash screen on load (for 6 seconds) reminding you to generously purchase reaper!
- something along those lines - I forget & I never bothered with the program.
see now what you are saying about the 8bit/32bit is confusing.
for me to get .png with transparency to work ok in VS I have to use the settings shown in the attachments I added.
