in reply to Win32 limit to number of calls to system()?

There is a per process OS limit on the number of filehandles ... see FileCache/_setmaxstdio

It might also be a per-process-group limit

Use http://live.sysinternals.com/handle.exe or http://live.sysinternals.com/procexp.exe to examine the process details and open handles before hitting 64 and after

Maybe the program doesn't die, and keeps a lock open to some config file or something, thus blocking subsequent ones ...

    Anonymous Monk,
    That certainly seems plausible but it would mean shame on Windows for not actually releasing resources when the program is shut down (unless using alt-f4 is a bad way to close the program). Perhaps before I write all the code to keep the app open, I will try closing it through the X button.

    Cheers - L~R
