Not at first look but when you play with the finder, it becomes clear :)

Great work, very neat tool.

One minor improvment:

Let's say I have two panes A and B. In pane A, I have a list of CompiledMethod and I select Object#=

Then the code for Object#= is displayed in the bottom pane, and pane B is filled with field values of the CompiledMethod instance.

Then if I play with the buttons in pane B to get the senders/implementors/messages for�Object#=, the bottom pane is cleared.

I feel like it should still displayed the current selection (in pane A) until I make another selection.
