its a windows application.

I suspect that that the window you are seeing is being created when the C++ app spawns Perl; rather than when Perl calls system; and unless you have access to the sources of the C++ and can modify it; you may be stuck.

The only suggestion I have that might fix it without modifying the C++ app is to swap your call to system, for a call to Win32::Process, and try using the CREATE_NO_WINDOW flag.

If that doesn't work, see above.
