High CPU when generating report

[zenking]

I'm running Zen 6.5 sp2 on Netware 6.5 sp7, and have C1 locally installed to my XP sp3 workstation. I have set up ODBC and successfully tested my connection.

I can get results from an inventory query with no problem, but when I try to generate one of the canned software reports and search for 1 piece of software, my C1 starts using a ton of memory and the CPU on my server jumps to 97-100% and stays there. After about 4 minutes, no results in my report, so I killed C1 and everything went back to normal. We only have about 300 workstations in inventory. Aside from the reporting problem, inventory seems to be running just fine. Any ideas what might be causing this? Thanks.
