has anyone come across something like this?

Frequently. And it's undoubtedly the error 429 that Steve alludes to.
It's a problem in registering some of the .ocx and/or .dll files in TM1. I'm not sure exactly which ones will trigger it, though I
believe that at the time that TM1 loads the one that it's trying to register is tm1xl.ocx.
As I understand it, this is what's used for the In Spreadsheet Browser (ISB). The good news is that if you wait for the release after 9.4, they'll have discontinued the ISB anyway.
The bad news is that (in 8.2.12 at least) it doesn't matter whether you want to use the ISB or not; once you hit the 429 error everything stops and the TM1 menu item won't appear on the toolbar.
We started to have the problem here when the IT department changed the level of access on users' deskttops. Originally everyone was in the "Power Users" user group, and the files would register themselves correctly. They've since downgraded new users to the common or garden "Users" group. Members of that group can't install software, and also can't register ActiveX controls or .dlls. Part of the reason that I.T. did this is that apparently the Power Users group doesn't exist in that bleeping abomination Vista, and they're getting ready to eventually migrate to that platform. Hopefully later rather than sooner, may I add. (I can't confirm that from personal experience since I haven't used Vista extensively enough to have gotten into its security group settings. Aside from which I feel the need to take a half hour bath every time I touch the thing.)
The only workaround we've had to date is to have I.T. desktop support manually register the controls and .dlls (we currently pick the add-in files up from a network share rather than installing the client software on each desktop), though they're planning to create a script which will automatically register them when they get the time to do so.
By which time maybe we'll be on 9.1 SP4, and there will be a whole new set of issues.
