[Wine] Windows Help files

[Stan]

I have a shareware product that I sell that is windows only (due to the development system, it never will be ported to Mac or Linux). I have been testing it on WINE for about two years and now it almost works with latest version.  I want to pass on some info to the makers of the compiler (so mine and other apps will run under wine).  One problem I have is that the CHM Help system does not work on Wine (works on Win 98/ME/2000/XP/Vista). Is this a normal Wine problem (I know old style Help files .HLP  load)?  Thanks for any pointers/info you can give me.

Cheers,
Stan
