Hi, I've moved your thread to the Xara Xtreme forum as this is directly related to Xara Xtreme.

As for your site. No problems here in any browser, loads in a couple seconds.

However you might try naming some of your photo graphics as 'JPEG' in Xtreme before export, this will force them to be exported as .jpg rather than the default .png (which are bulkier and slower to load).

Just select the image and press the yellow tag icon on the tool bar then name it JPEG.
You can do this for all photo graphic images (it will complain that the name already exists, but just ignor that).

As none of the tab links work, I assume your site is unfinished
