As soon as I click on nwadmin I get a blue screen that says something
about a tread (I think it says not releasing)I didn't get the entire
message and it reboots my PC. I loaded all 7 of the patches that were
released yesterday. I'm not sure but I think that nwadmin worked fine
before the patches.

I uninstalled 4.91 SP3 and installed 4.90 SP2 Patch kit D and nwadmin
works fine.

I may try to uninstall 4.90 and do a fresh install of 4.91 SP3 and see
if it works.
