AutoCAD Architecture :: Toolpalettes Disappear On Startup?

I though maybe this was a 2010 issue, but here I am in a brand new 2012 setup and experiencing the same problem. For some reason, my toolpalettes disappear on startup and sometimes when switching between projects. I have my workspace saved with  the following anchored to the left side of the screen: Properties, External References, Layer manager, Project Navigator

Design Center, and Toolpalettes. When I close Acad (or it closes itself) and restart, sometimes the tool palettes are there and sometimes not. All of the other palettes are there save that one. They also have a habit of reordering themselves if you pin one open and the minimize it it drops to the bottom of the page. Very annoying when you think your PN is at the top, and it isn't, but i digress.

I am working with Windows 7, 64bit, dual screens. This happens with equal frequency in both 10 and 12. (Working in 12 to develop rollout for office and working out kinks. No I do not run them both at the same time.)

One more clue, I noticed in the command history that TOOLPALETTES loads and is followed imediatly by _ToolPalettes.
