So, I went and did the "Show Package Contents" method, and that opened it up when I double-clicked the "Mac_Runner" binary. Not sure why that works, but neat-o! Just doesn't connect to the parked dock icon is all.
Damn that’s weird, glad it’s working for now. I’ll have to cop the update soon and have a look. Will keep you posted on the svg stuff although I should probably get saving/loading working first. If you happen to try a png > svg tool let me know if the output is any good.
