Hi Dom,
Good news, the new build works fine. I did have one small issue, when I was trying to change the font of the text it didn't want to change, I tried selecting the text and then changing the listed font, I also tried selecting the font and then typing some new text but it kept going back to the default. I did manage to get it to change once but I'm not sure what I did to get it to work.
I guess I am a developer but I don't think giving me the files would do much good. I don't even know what language you are using. I'm currently learning video game development at university. One of our projects for game design was to develop a board game, I enjoyed it so much I'm trying to turn my project into a fully developed game.
Are you still developing this tool? If all goes well I'm planning to test my game on Table Top Simulator and after that onto The Game Crafter.
