--- Comment #5 from Paul Romanyszyn pgr@arcelectronicsinc.com 2008-01-05 11:31:34 --- from winevdm.c line 218 if( (p = strrchr( progname, '.')) && !strcasecmp( p, ".bat")) WINE_FIXME(".bat programs in pif files are not supported.\n"); I did look a little into the problem but did not see enough info to implement it without spending a lot of time. The application that I have requires it also uses a hardware key so I have to run that software on old system with Win 3.11 or Win 95.
