Trouble with downloadable PDF files

We have downloadable PDF files (patterns) on our site (ZC 1.3.9a). They seem to download and open fine in Firefox, but in I.E. the download appears to stall -- the user gets a blank page and I.E. freezes. There is some indication that there are pages present, but you can't see them.

What's happening here and how can we make this work?

Thanks,

John

PDF product downloads in their core format can be problematic, because browers like MSIE are deliberately construted to try to auto-open them. (I HATE MSIE !!!)

The only practical solution is to ZIP the file (even if it is just one PDF) so that it has a .zip extension.

MSIE can't mess about with that.

Later versions of Windows will have an unzip function, so your customers will not be inconvenienced if they don't have a priprietary ZIP program on their machines.
