Having problems with Leopard, MCX with OD server and MS Office 2004

Hey all, I'm having a problem I've never seen before, I'm trying to setup some Application limitations for Mobile student laptops. I've gone in to the Applications preferences and enabled everything I can find for Office 2004, but no matter what I do there is a small application by the name of FontCacheTool in /Applications/Microsoft Office 2004/Office/Support Files/FontCacheTool that will not run. I've tried dragging it into the list of 'allowed' applications, adding the folder, etc. WorkGroup Manager seems unable to ID the application - could this be because of a missing CFBundleIdentifier as this is identified in the Finder as a Unix Executable. Anyone else experience this? Or get it working? I've done this before with Tiger with no problem. The only differences now that I can think of is first that this is Leopard, and second that this is a French installation rather than my normal English ones. Jeff
