Thanks!
That is definately on target, but didn't seem to help.
I looked and the quicklaunch folder is there and contains what looks like the right items. Re-registered the dll's, too.
I think the problem is Windows isn't remembering my desktop settings (task bar, toolbars, icon placement) through a shutdown / boot up. I've check the registry settings for "nosavesettings" (Explorer Policies), but the ones I've found are set to "0" (save settings). Something else is stopping it from remembering through a reboot, but I can't find it.
