NotePad is working fine. I the problem is that you are using
DDEOPN32.EXE. I tried to associate .txt extension to TextPad and when
I am opening any text file from Windows Explorer then it is working
fine. From Tools/Folder Options menu in Windows Explorer you can see
that it is launching TextPad directly through DDE. Some times ago I
was using TextPad in this way and it was working fine. Unfortunately
currently I can't remember the details. I think that you should use
the DDE API directly.

It was a long time since I used Hugs for the last time. Usually I am
using GHC but I was curious to see how the new WinHugs looks like. The
"Add" button should open a dialog where I should be able to select a
new Haskell module to load in Hugs.

It is strange and it is inconsistent with GHC.

ok.
