SYSTEM32 folder opens on startup!

One of my XP systems is now opening the "system32" folder each time someone logs into the local computer.  I have checked for virus infection, ran spybot and adaware, and ran hijackThis on it but cannot figure out what is causing this.  I have also tried the #260 tip listed in other threads but that runs and says there is no entry of that type in registry.  I have checked the registry RUN commands but have no strange entries there.  I have disabled everything in the MSCONFIG startup items and that does not help either.
Here is the info I copied from HijackThis...
