I opened a PNG file to work up a logo. I added some text, a new background, knocked out some white areas. I was just about done and thought, oh, I should save this. When I tried to save it, it said that it contained non-pixel areas and did I want to save it as a new document, which is what I chose. The file, as near as I can tell, was not saved.
Now, I have access to only a few menu items and every item I click on in the interface beeps back at me. Saving is no long an option and even quitting isn't allowed. I'd rather not throw out 30 minutes of work, but I can't figure out what mode I'm in that wouldn't let me get of it and save.
Any thoughts or will I need to force quit the application and start over from scratch in Pixelmator?
