Ever seen this? See attachment CBproblem.jpg, or jump to the site directly:
lustenau.permatop.at/index.php?option=com_comprofiler&task=lostpassword

Description of bug: The upper area of the page, including CB login module, is shown again under the end of the page.
This happens on many CB tasks, e.g. task=lostpassword, task=registers, etc. It never happens with other components than CB. I once switched off all other modules one by one, but as long as CB is enabled, the bug happens.

Environment: I'm using Joomla 1.5.x, CB 1.4.0. It happens with all templates, and it did happen with CB 1.3.x, too, before I upgraded.

I fight this for a long time now, but I have no idea what I should do against.

Any help would be very appreciated!

TIA, svogel
