Since upgrading to Toad Datapont 6.4 the grid count keeps disappearing. If I run a script it doesn't show the grid count. Going into Tools ->Options ->Environment ->Grid and "Show Navigator Panel" is selected. If I unselect and reselect it and hit Apply the count shows up. When I run another script it disappears again and I have to go apply it again for it to show up. It doesn't appear to keep the settings even though they are selected.
I've downgraded to version 6.3 and the problem is resolved. I guess 6.4 still needs more time to work out the bugs.
