PR# 16613 Wrong cursor or no cursor shown for class or feature picked from Dependency tool

Right-clicking on a class or feature in the Dependency tool correctly
starts a pick (with PND mode enabled in preferences).  However, 
picking a feature changes the cursor to the class cursor (oval) instead
of the feature cursor (cross).  Sometimes, the accept cursor is nothing for both class
and feature picks.

Start estudio and compile class.  Make sure Dependency tool is shownb.
In Dependency tool, click on "(no class)" and type ARRAY in popup window.
Expand "+" signs until you see a feature.
Right click on feature `Minimal_increase' and move mouse.
There is no cross shown for cursor.
Right-click on RESIZABLE class above `Minimal_increase' and move mouse.
No oval shown for cursor.

Now right-click on ARRAY (first line in Dependency tool) and move mouse.
Correctly shows oval for cursor.
Right-click again on any other class or feature in Dependency tool.
Shows oval for cursor for class, but also for feature.
