Are you specifying INFINITE for the timeout of WaitForSingleObject()?  If
so, then specify an actual timeout value, such as 500, and then call it is a
loop that also calls Application->ProcessMessages() or at least Update(),
ie:

    while( WaitForSingleObject(ShellInfo.hProcess, 500) == WAIT_TIMEOUT )
        Application->ProcessMessages();
        // or MyForm->Update();
