Hi tatteredking and welcome to the Guild.

I've never used Dundjinni, but I know Bogie, another Community Leader here, uses it extensively. Not sure if there's a workaround for the Windows 10 problem, though Bogie may have some advice.

If you need some help getting going with Photoshop, there's lots of help and downloadable tutorials in our Tutorials/How To folder.

Look forward to seeing some of your work, and if you need help with anything, just ask.
