Small js issue

Hi all, I’ve recently upgraded to 3.0.1 along with upgrading all of my plugins (currently Twitter – the xhanch one, Slidepress and a Facebook like button).

Since the upgrade I’ve found my blog to be slower than normal (scrolling, not necessarily loading) and I’ve got a js error in my status bar. The error reads as follows……

Webpage error details

Any light shed on this would be vastly appreciated – earlier I was also finding it difficult, and in some cases impossible, to open a “_BLANK” link in my blog posts – this *seems* to have cleared up for now!

Finally, I’ve re-downloaded the zip file and replaced the file in question, no mods (I don’t really know javascript) and still the same problem.

Many thanks 🙂

Richard.
