Windows.Inc doesn't include the MB.CANCELTRYCONTINUE option that works for Win2000 and above. It displays Cancel/TryAgain/Continue. SET should be = 6
When MessageBox first came out, I built my own INC file for use in all my programs. I put in just the options that I thought I'd use. At that time I included some of the button responses. Can't find the original that I used. Through testing I've found that TryAgain returns a 10 and Continue returns an 11.
Another option, that might be useful on machines where Comet is running as a service, is the MB.SERVICE.NOTIFICATION.
