This is not really a problem more an annoyance. In trigger overview, hosts are redrawn in no praticular order (as far as I can tell). This is a little annoying when you are refreshing the page, you have to keep looking back up to check what column you are looking at.
Has anyone experienced this kind of problem?
This was discussed before. Hopefully, ordering options will be included in the next stable release!
There is also a patch for this problem, which works perfectly for me with Zabbix 1.1.4.
PATCH: Hyperlinks in overview.php (Zabbix-1.1.2)

Simply move to your zabbix html diretcory and do a patch -b <originalfile> <this_patchfile>
The "-b" option produces the backup of the original file, if the patch breaks something.
Fixed. Thanks for reporting this.
