monitor window not showing last events

[mcarro]

Hi, I'm running Zoneminder from Debian Stable (1.24.2). This week after a security update for mysql the monitor window stopped showing the latest events. The column headers are shown but no events, as if the camera has no previous events. Going to the filter window or clicking on the filter columns does list the events without problems.
The logs show no problem. Any hint? Where should I look?

Ok, just for the record, I found the problem: I had replaced (and forgotten that I did it) the Debian provided mootools package by the latest version from mootools.net. When I went back to the Debian version everything started to work OK again.
