I just installed this running 6 templates went through brilliant the first time I am using IE I have tested it about 50 times with sending and recieving not got any errors on any templates the pages go through on all templates seems to be working perfect I dunno if this helps but I am running windows XP sp2 (locally) all up to date updates server side I have php 5.0.5 and mysql 4.1.14-nt appache server I am not finding any problems with this at all..maybe there is not a bug in this hack but more a bug depending on what versions of things are being run on servers, versions of windows, mac etc because the hack appears to be working itself just depends on whos running what this is a awesome hack easily installed in less than 5 minutes on my site with all the template changes excellent work very very nice..
