Widget causes error with Portfolio Slideshow plugin

Hey guys,

I really love the Fixed Widget but on a site I manage I have a conflict with the Portfolio Slideshow Plugin. Somehow whenever the slideshow loads the page jumps to another spot.

At first the Portfolio Slideshow didn’t work at all until I activated “Use jQuery(window).load() hook:”.

Here’s the page I have the problem with.

The fixed widget is the Newsletter Signup Form in the right sidebar.

Any ideas how to fix this?

Thank’s in advance,
Hannes
