[TYPO3] install tool doesn't update database

[Christoph Koehler]

Hello there,

This is a problem I have had for a while: I cannot update the db from the  
install tool compare. Using TYPO3 4.1 now, MySQL 5.0.22, PHP 5.1.2, Apache  
2.0.55.
It reloads the page, but the modifications are still there to be executed.  
Checking the db with phpmyadmin confirms no changes.

Thanks!

Christoph
