I’m getting a rather strange problem where I cannot compile to ePub from the Compile dialog. I press the Compile button but it does nothing. Can you replicate? I can send the project file if you need it.
EDIT: I just found out it does it on Kindle .mobi as well.
Hm. The problem is that you need to insert Title, Author, and Date meta-data in compile. There used to be a message that popped up and told you this, and it was even updated in the internal betas, so I’m not sure what happened to it here. Anyway, to do that, click the blue arrow button to expand the compile panel and then click “Meta-Data” on the left and just fill in those three fields. Once you’ve done that, you should be able to compile.
