My order: 00018047

Try to edit a customer in the backend: Check the box left from the customer name and click "edit". Now change something or add something and click "save". The changes were saved, but the whole Joomla-Menuebar disappears and you are not able to do something. You have to close your browser and log in again.

I noticed this bug in version 1.2.5 and in the newest version 1.2.7. (don't know about 1.2.6)
I use Joomla 1.5.23

Any help would be appreciated! Thank you!

Anybody?
Am I the only one with this problem?
Thanx in advance!
