Q. How come when I change from Design to Analysis mode, or visa versa, sometimes the results do not match?
A. For your convenience, we allow you to easily change between modes. SubPUMP transfers the data when this is done. However, we strongly recommend that you check all the data when you switch between modes.

Q. I recently switched from Windows 95/98 to Windows NT/2000, and my bitlock application no longer works, what happened?
A. Windows NT/2000 has a different internal architecture than Windows 95/98/ME, and requires a special driver to be installed before accessing the bitlock. We have included bitlock drivers and the utility required to install them with your application product in a self-extracting zipfile named "Rainbow.exe".
