--- Comment #16 from Owen Rudge owen@owenrudge.net 2009-07-22 13:07:54 --- Is an error message or a backtrace printed in the console? Exactly what steps did you take to get this result?
For me, opening winhlp32.exe, cancelling the Open dialog, and choosing Help on Help gives a "cannot find winhelp.hlp" error message, as it should.
