Downloading zip files

Hi

Having problems downloading zip files from the forum. I'm using win7 and IE.

When I try to save a zip file, it downloads as a attachment.php

An example in below link, Post 298 -Nokia Big Chars.zip

http://www.picbasic.co.uk/forum/show...ighlight=nokia

"Do you want to open or save attachment.php from picbasic.co.uk?"

I tried renaming the file to zip without luck

Thanks
Mark
