catalog view blue disappears

Everytime I save or apply a change to any of the output views, the blue bars dsappear and Im left with just the text. Very weird.

I am running Firefox 3.6.8 and:
Joomla! version: 1.5PHP version: 5.2.6MySQL version: 5.0.87
I have to reinstall to get it back.This is urgent, please can u help?

Same for me.
Everytime I save a category view the list does not work anymore... any tip how to fix?

Got exactly the same problem!
I've done a copy of the original joodb_sample table to test it.
Maybe the problem is a css or html problem, because the source of the page doesn't publish the correct content (pictures, etc.).
Any suggestions?

Its not a joodb bug. The editor removes CSS style informations. But there are 3 possible Ways to prevent this.
1: The most comfortable is to install the Joomla Content Editor JCE and enable ALLOW CSS in the Croup config, set Cleanup HTML to no and Entity Encoding to Raw.
2: Disable the Editor and work with the raw HTML code or use an external HTML Editor to create the template.
3: The cleanes way is to use the Styles from the Template stylesheeet.
I only included the CSS informations in the template of the sample database, because i want to show whats possible.
