Hmm, off the top of my head I cannot think of a reason why it shouldn't be working for you. I'm on a PC but as far as I am aware the JVM should translate it faithfully. I might be wrong but I thought that as long as I stay away from referencing specific windows commands or keys then it should be ok cross-platform. Can anyone else verify this?

Unfortunately I don't tend to get a lot of feedback here. It's been downloaded 22 times so far and only a few people have commented so I am never sure what problems, if any, people are having. I'll take a look into it and see if I can find a problem with the saving, although why it would save the image and not the layers I don't know. :S

Anyone else had this problem? If so are you on a mac?

Just out of interest though, on the mac does the program appear graphically similar to how it was in the last screenshot that I posted? I have often wondered if the LookAndFeel would translate correctly across platforms.
