Excel 2007 : Excel 2007 Vista

[Horse87]

Here's an odd problem we're experiencing;
Several of our users have had Excel 2007 installed as part of an upgrade from Win2k to Vista, and we have found that some of them are now noticing that when trying to protect a document, they hit 'save', go to the tools drop down so they can then go to the 'general options'....but all they have is 'map network drive'. Nothing else is in the drop down.
None of us can figure out what the heck is going on. We've looked everwhere for info on this problem, but we haven't found anything.
It's happening on several workstations, so it's unlikely it's a corrupt install.
Has anyone seen this before?
What did we miss?

Understood.
I should have been more exact and said they are looking for the option to recommend a read only document. It should be in the tools drop down found in the 'save as' box, but it isn't. In any case, other than 'Map Network Drive' all the options, (Web Options, General Options, Compress Picture) are absent. However, under the administrator login, the options are present! Wtf?
