Clicking on a Google link ad from this site (to Cube247) I get an error message saying I need the Zend optimizer to view the site and to download it. Here's part of the message,
"The component "Zend Optimizer" is not installed on the Web Server and therefore cannot service encoded files. Please download and install the Zend Optimizer (available without charge) on the Web Server."
I have not heard of this before and question whether I really need it and indeed whether it is for Vista. I have tried a bit of Google exploration but I am into day 3 of my mother in laws visit for her 90th birthday celebrations so my grey cell is a little strained at the moment.
