Hi Duncan,
Thanks for your comments. In the context of a haskell process running as a Windows service, a message box is useless, because Haskell services do not have a GUI and cannot interact with the desktop.
Good point. Perhaps you can persuade the people who look after GHC on win32 to have it use the Windows debug log service for exception messages like that when there's no GUI available. Of course if you can code up and submit such a patch yourself then even better.
Sounds like a good idea. You need to look at rts/RtsMessages.c, in particular rtsErrorMsgFn(), which currently has cases for GUI and non-GUI. I guess it really should have 3 cases: GUI, console, and non-GUI. Cheers, Simon
