Trying to get the Ignore button to work eventually cause seg fault. A workaround is to bracket calls to these functions with SetErrorMode((SEM_FAILCRITICALERRORS | SEM_NOOPENFILEERRORBOX)); /* disable SEM */ and SetErrorMode(0) /* enable */ This effectively presses Ignore for you without the SEM dialog: GetLastError returns 21 (ERROR_NOT_READY) which is what the Ignore reponse should do.
