I installed Bob's UI (3.0a) from SqueakMap just now.  Then I opened SM Package Loader and selected "set download directory" from the menu.  When I ran the mouse over the expanded hierarchical list of directories, each element I moused over was highlighted in turn -- and the SqueakMap download directory changed to that newly-selected directory. The only way I found to *keep* that directory selected, was to move the mouse out of the hierarchical list morph and then carefully click the OK button.

Is there a preference to disable this mouse-over-selection behavior?
