I meant this reply to your other post:

"Check out MSKB Q221696, see if that's related. Supposedly SP3 has fixed it."

But if you're using SP3, who knows if it's related or fixed? But take a look at that article at the MS KB, and see if it is in any way related to your code. That is the only MSDN article that looks relevant. Something about docking toolbars.
