Null Reference Exception" error when changing object/schemas filter. (4234373)

When working in Toad a "Null Reference Exception" is given when trying to work with filters in the Object Explorere. This is only an issue when the Navigation Manager is closed.

Steps:

1. Go to View menu | Navigation Manager to close the window.
2. Go to Object Explorer and click on the object or schema Filter icon (or the drop down for the filter). 

Trying to work with the filters will give the error.  

WORKAROUND:

Keep Navigation Manager open.

If more room is needed in the Toad window, the Navigation manager can be pinned so that it slides closed, and can be opened for reference when the mouse cursor hovers over the tab.

STATUS:

Waiting for fix in a future version of Toad Data Point.
