Not sure what I did. From time-to-time I manage to stumble into something
within VS.NET that makes no sense, can't be searched in "Help" (I mean, how
do I search on "icons" such as blue-boxes?), and find digging out of my
condition sometimes difficult.

This one wasn't a deal-breaker insofar as it didn't actually affect anything
(and went away, for some reason). However, simple things like "docking"
behavior can sometimes be a tad confusing when my expected look-and-feel
unexpectedly changes on me. Although obviously powerful capabilites, if it's
not something you actually need and stumble into it, it can be a real pain
to get back to where you WANT to be.
