I can't reproduce that.  I get forward slashes only. Can you track down
where the \ are coming from?

Well, I have and Firefox works properly, for example.  I've not used
Mozilla recently as Firefox seems rather better.  I also checked, and IE6
works too.  Do you have a browser set (options(browser=)), or are you
relying on file associations?

Since this is to be a file:// URL, I believe forward slashes are correct,
but we are at the mercy of Windows browser providers.
