Got a little exuberant using Add-Ins in Visual Studio. Not sure which
add-in caused the probem. To remedy the situation I:
1) shut down Visual Studio
2)went to (on XP) C:\Documents and Settings\dklug\Local
Settings\Application Data\Microsoft\VisualStudio\10.0 and deleted the tdb
files.
3)restart VS and right click in the toolbox section> choose Show All
