To fix this you would need a small modification of the default source – you need to find/replace the following:
If you use the minified version, just use double quotes prevAll("a").
I actually think this is a good generic tweak so I will make sure it’s added in future versions so you don’t need to worry that you could lose the fix if you decide to upgrade the script in the future.
As for posting HTML code samples, just replace the opening <'s with <'s for now. I will surely fix this when I have a bit more time..
