I'm using IE6 and all plugins are disabled. It's a brand new installation in french.

What browser are you using? Have you installed any plugins which change the styles of the application (adding features, etc) or replaced any of the /tmpl/ or /mt-static/ files?

Im using IE 6.0.2900.2180. and it's a fresh installation with only one plugins name EnhancedEntryEditing. No template changed.

If you disable the plugin, does the application display correctly?

No, ALL plugins is now disabled and the problem persist.

You can close this thread. No solution found, i chose another product. Thanks for your support.

This is definitely an issue with the latest EnhancedEntryEditing plugin. It somehow forces the entry box alignment as a block element under the side bar...
