IE9 hyphenation problem - hyphen at start of line

In IE9, some posts on our blog hyphenate strangely, with the hyphen appearing on the line after the word break. For example, in http://yochicago.com/airbnb-%E2%80%93-illegal-short-term-rentals-galore/23326/ "short-term," in the first paragraph, breaks as follows:

short

-term

I've seen this a few other times with this site and another site in development. And o开发者_运维百科nly in IE9. Compatibility mode "fixes" it.

Since I've been unable to find others writing about this same problem on the Web, I can only assume I've got something amiss in my CSS, but I can't figure it out.

So, two questions:

1. Is anyone else seeing this behavior in IE9?

2. Any suggestions on how to fix it?

I don't know what is causing the problem, but a quick fix is to apply:

<span style="white-space:nowrap">short-</span>term
