OK,I will run the install for 1.5 rc4.
before doing anything else, I will copy the zipped files into the
default folder rc 4 creates, (including putting the newer fbclient
and gds32.dll in the OS\system)

Then a reboot. after that, do any configuration needed. and it
should work, correct.

btw, ibconfig should also work with the new 1.5 shouldn't it.
