odbc

Hi all, this workded fine in rc1, but problem in ful version:
I am using an odbc call from an access database to an as/400. First time
after reboot, works fine. Second time it fails, then I have to reboot.
Also noticed a large slowdown in using pkzip or pkunzip in a command
windows. Now when I run pkunzip to look at the contents of a zip file, it
takes 5 seconds to return the results. This was instantaneous in rc 1. Any
insight would be appreciated.
Thanks, Wolfgang
