If I use profiling on windows with relative path names e.g. the first line in the .hp file is something like: JOB "ScriptUsage.exe -t ..\FPF\TradeDesc\TradesTags.txt -f ..\out\FPOs - u ..\Data\LogStarted090511c +RTS -H256M -hc" then hp2ps produces nonsense. If I replace this line with: JOB "ScriptUsage.exe +RTS -H256M -hc" then it works. Is this a known bug or should I try to raise one? Thanks, Dominic.
