[Haskell-cafe] Problem with packet documentation generated by cabal on windows 7

Hi cafe, I have a problem with haddock documentation created when installing new packages with cabal on windows. The generated html files have all links in the form j:\Users\...\doc\...\xxx.html, but firefox says, it cannot open that link. Actually all links should be prefixed by "file:///". I wonder if this is only on windows so and if there is a solution to this. Is there a cabal or haddock flag for this? Nicu
