Does anyone else have problems after upgrading to the latest version of Spybot Search&Destroy (1.5.2.20)?

The upgrade seems to cause problems with the CookieSafe (2.0.6) add-on for Mozilla Firefox (2.0.0.12). From my experience so far, S&D slows down the browser significantly. Firefox stops responding sometimes when I load a website and in Task Manager I can see that the browser uses ~99% CPU. Also, I get the "non-responsive script" pop-up whenever I try to (re)load a website

Code:
A Script on this page has stopped
working....

Stop the script                  Continue
and I am not running any add-on to prevent scripts from being executed.

I have been able to reproduce this problem on four computers. They are all running Windows XP, Firefox with CookieSafe add-on and Spybot S&D and show the same behaviour after upgrading Spybot S&D.
As soon as I disable/uninstall the CookieSafe add-on, Firefox is working again without any problems. This seems to be the only fix I can come up with at the moment.

Can anyone confirm this?
