Hello all, I'm experiencing two problems at about the same time, I do not know if they are related: After setting an option for winhugs, using the GUI, Winhugs refused to start, displaying an error message about expecting another double quote. I solved this by changing the Options in the registry: HKEY_CURRENT_USER\Software\Haskell\Hugs\WinhugsNov2003\Options had the following value: -s -t -g -G -l -. +q -Q -w -k -o -O +u -I -T +A +R -H +98 -h250000 -p"%s> " -r"$$" -P".:{Hugs}/libraries:{Hugs}/oldlib:{Hugs}/libraries/win32" -S".hs;.lhs" -E"C:\\WINDOWS\\notepad.exe" -c40 -F"" " I removed the double quote at the end. The error message about the double quote is now replaced with the message: ERROR - Unable to open file "C:\PROGRAM FILES\HUGS98/libraries\Hugs\Prelude.hs I am running: Hugs '98 Nov 2003 on Windows 98 -- Best regards, Henk-Jan van Tuyl
