ISSUE: Problem with binary file formats under IE6

Hi there,

we have the phenomenon, that we get error messages ("..document could
not be opened...") when clicking on links that represent binary files
(like .ppt or .doc) under IE6 and websvn.
It's funny that the same procedure works fine under Firefox (i.e. we can
open such a file with the suitable application).
What we tried so far is using UTF-8 instead of ISO-xyz and we added
the mentioned file extensions in config.inc -> no success.

Does anybody know what is going wrong here or what's missing ?
Best regards
Valentin Treu
