I am trying to chain together 3 post NC4.91SP2 patches by suppressing the
reboot of the first 2 until the 3rd has been installed. However the
reboot message appears after the first app has installed, and I have to
click NO to continue for the 2nd app to be installed, and then have to
click NO again for the 3rd app to be installed.

Why are these reboot messages appearing when the suppress reboot option in
the chain has been selected?
