the nag message may appear in 2 situations:
1 - when redistributing the trial version of the ocx instead of the full version (they come with different installers)
2 - when invoking the InitRecorder method at a too earlier stage during the container application's life, for example inside the constructor of the container form or dialog box instead of the initialization handler (WM_INITDIALOG for applications developed using C++)
Please, let me know if one of the 2 points may apply to you and the development environment and language currently in use (for example VB6, VC++, Delphi, etc.).
