Good. I tried it again with quotes around the "+relay" since I missed
that fine point. Didn't change anything much.

Yep, it does. That was one of vitamin's comments early on that I think
you nixed at the time. No big deal. Either way it would be good to get
it looked at.

The app is an old, old game called Lighthouse:The Dark Being which I
never finished in the old days or running Win 95 or Win ME. It came
out in about 1998 and isn't sold anymore. The item that fails is a
small section of the app that tests the system for compatibility. In
the thread called "CDROM detect failed" a couple of days ago I posted
a small PNG file that showed the part of the app that fails. There are
a number of button you push to check things - OS, graphics, processor,
CDROM, etc. Two fail consistently - the CDROM and the processor.

The best link I have right now is in the bug report:

http://bugs.winehq.org/show_bug.cgi?id=2555

The link above has a download button but you have to be a file planet
member to get it.

There are other links on the web about the game:

http://en.wikipedia.org/wiki/Lighthouse_(computer_game)

It's generally in the Myst genre but harder puzzles to solve, or so I felt.

I'll look at adding +seh, zipping the file and submitting it in the
next hour or so.

Thanks much,
Mark
