Semtools

From the madlib (column) view:
-click a class selection field
-pop up shows
-try to expand the root node
-popup closes

Turns out the focusLost event is being fired in windows and the popup is closing (like it's supposed to when the focus is lost). But the focus shouldn't be lost since the popup should be a whole new context.

Worst case scenario I can take out the focusLost listening, but I think I can make the popup more independent from the focus model of the class selection fields.
