Problem with two files I uploaded

[Guest ovavp]

I have uploaded two small apps recently, but have now discovered a problem with them that did not show itself in the admittedly minimal beta testing I did.It seems that the apps will not run on Window NT, 2000, or XP Pro. As far as I can tell, it has to do with Microsoft Foundation Classes 4.0 being incompatible with those OS's. I am very new at programming and did not realize this would be a problem.My question is this: How do I replace the uploaded files with new ones that include a statement that they are not guaranteed to work with those operating systems?I am continuing to track down the problem and if anyone here knows anything that might help me, please pm me and let me know. The two apps are ApproachCalc and DescentCalc. They were built using Visual Studio in the C# language.Thanx for any help you can give me. I don't want to just leave people hanging not knowing why the apps won't work for them.Brian Wilber
