Editors fail to update with cursor and selection

cu8.05, win 7 64bit

See screen shot: select track data, set cursor to desired spot (bar 3) in Project Window.

Open List Editor: The cursor and view range background (right side) show correctly but the notes and controllers that are present at bar 3 in the selected tracks are not shown. On the left side is a list of events from the previous area of work, bar 33.

It should be impossible to arrive at this configuration!
