Gnats 4830: When editing data in slots, TAB key moved to next cell but
 keeps first cell selected. [RiverWare 5.2, 5.3].

Sequence in an Open Table Slot dialog (Reservoir Elevation Volume Table --
a two column Table Slot) when entering these four keys in a cell in the 
first column: '9' '9' '9' TAB ... and then clicking in another cell.
[When hitting TAB, the stated problem is exhibited].  Note that the first
'9' key entry initiates an incell edit.
