How to rollback in local VCS?

I used to be able to rollback in the Local VCS window by right-clicking
on the items in the "Version" or "Action" columns.

Now that I'm using IDEA in Mac OS X, I get no menu when I right-click.
Is there now some other way to rollback in Local VCS, or is there a Mac
OS X bug that is causing right-click to not show the menu?
