Of course you'll have >to dig a bit trough it's docs before you find any mention of that little >fact... Sorry I did not mention that detail. I did buy the professional version so it has the optimizer. In fact, as I mentioned, it optimizes very well if I ran the executable on a pentium II or III (the ones I tried). BTW, another issued is that I installed the "processor pack" that is in the microsoft.com web site that is supposed to have optimizations for pentium III, but I don't see the new options on the pull down menu. Is that correct? Regards, Miguel the options on the compiler. > >-- >GCP
