Text has turned to minus-tracked jibberish
On reopening my Keynote 5.3 file all the text has turned to severely minus-tracked jibberish. So severely minus-tracked that all the letters are overlapping. I'm using a non-system font and when I change it to Arial the problem goes away. I'd rather use the font I've chosen though of course. Anyone seen this before? See screenshot attached. I'm on OSX 10.8.5
MacBook Pro (Retina, 13-inch, Late 2012), OS X Mountain Lion (10.8.5)
