>George I had the same problem with some NT4.0 workstations that already had SP3. The problem went away the moment I re-applied NT4.0 SP3.

Juan, I did re-applied NT4.0 SP3 and did not solve the problem.

Besides the frustration am going through because of this problem, what bothers me most is than I did not receive any answer to sush a vital question (problem).

Does vfoxpro5 requires a special kind of installation in windowsNT OS?

Thanks for your reply.
