I'm in 2015.1.2, and I noticed as I'm trying to add bleed to a document, that my artboards are not sizing properly. The document is in 1200px in height, and when I change to inches, it enters it in as 1200 in, alerts me that the max is 444.44 in, and stalls the program. This happens for the width as well. I'm on OSX 10.10.5. Sorry if this is a bug fix that was already released, but I'd be happy to install if it is.
