There are a few things that are heavily used by most nasty VC++ programs
(__CxxFrameHandler, FI) that are not implemented yet in builtin msvcrt,
so if it is a VC++ app, I would expect you would have to use native
msvcrt, ant --debugmsg +snoop should trace calls into it.

That didn't come out as I intended.

Sorry, I am not much good with window messages and buttons.  It is a
regression, I see.  If you want wo work hard at it, there is a
procedure outlined in <wine>/documentation/cvs-regression.sgml to
distill it down to the very patch that broke things if you have the
patience and disk space.  Then you can go after the author to help fix
it.  Feel free to use this nasty little sed program to render sgml
almost human-readable, or use the other forms of doco at winehq or the
wine ftp sites.

Well, that I can help with.  Wine writes debug output to stderr, file
number 2.

wine --debugmsg +relay 2>&1 | tee logfile

is best for general use.

wine 2>logfile

wine &>logfile  (bashism)

script oops
wine <parameters> <program>
exit
