Description
Hey guys! First of all keep up the good work! ;)
I'm on OS X 10.10.4 and using MacDown v0.4.5.1 (647)
Soo... I found this little bug when resizing the panes to the left so you can read the document without getting bothered with the raw MD-text.
When the MD-pane is about 0 or 1 column wide macdown freezes completely and takes 98.9% CPU 'till you kill it. This happens only when you do it slow enough.
I illustrated it here:
Aaaaand its frozen! I got the "Spinning Beachball of Death" when i mouseover MacDown now (I didn't figure out how to take screenshots WITH the mouse cursor in them :/ just imagine it)
I hope this is enough information :)

Reproduce this on MacDown v0.4.5.1 under OS X 10.10.4 by slowly resizing the panes until the MD pane is about 0 or 1 column wide. Confirm that the application remains responsive and does not reach the reported 98.9% CPU usage or freeze.
