[jQuery] Div-Toggle doesn't work in IE

[jQuery] Div-Toggle doesn't work in IE


Hi There,
i'm new to jQuery and tried to toggle some divs inside a container
(with a click on the grey bar of the container). You can find the Site
here: http://dirth.stimme.net/jtest/jtest.html
In FF, my code works great but in IE (6 and 7), the divs only
disappear with a click, but with a second click they won't reappear.
Instead, the IE shows me a Javascript warning.
Can somebody tell me, whats the problem with my code in IE?
I first tried the slideToggle function, but it was extremely laggy,
and did not "slide" at all, what's the reason for this function to be
so slow?
Would be great. Thanks.
Daniel
