Dear winbugs: I have recently installed Haskell on a windows XP machine. The Hugs DOS interface works fine, but I am having trouble getting "winhugs" to run. I am getting a message: "Unable to open file C:\apps\Hugs\lib\Prelude.hs" I have already performed the procedure recommended in http://haskell.org/pipermail/hugs-bugs/2002-March/000658.html which is to edit the windows registry. Unfortunately, it is still not working. Can someone point an alternative way of soliving this problem?
