I have been running a program successfully under Windows 95 for years. We have upgraded several systems to NT workstations.

The NT workstations are getting variable-not-found errors (PG_DLGTITL ,a global variable) during execution. If I give the variable a value at the command line, the next variable in line fails.

The remaining Windows 95 installations run properly.

These systems are networked and are running the same executable and accessing the same databases.

The programs are Foxpro 2.6 EXE files with FoxFire! 2.5 app code as part of the .PJX file but excluded from the project.


Any ideas on what the problem is, or more importantly, how to fix it?
