Hi Nick,
1/the Nadya advice is reasonable. Your application do not care about company policy
2/Till now as I well red you use the best computer configuration for FP2.6, highspeed procesor work with low productivity and performance
3/For P3 computers you needs of special MS speed patch for FP2.6 for faster processor. My TechDirector Zlatin answer that kind of questions durring last week.
4/If application is 8-9 year old its time to upgrade/convert it this is advice of my husband. During Sales chanal going explanation that any DOS support was stopped.
