DBNavigator next button problem

I'm using dbNavigator to go through the results of my Query.  The next and back buttons will be enabled even when there is no next or previous record to go to until it gets to a non-existent record.  

For example if I'm on the last record of my result set the next button is still enabled (which I don't want it to be) when I click it the button freezes for a second or two then disables itself.  The back button does the same thing except there is no pause trying to go back farther than it can.  Any idea why this is happening or how to fix it?

Do a First and then Last just after opening the table. Sometimes, the BDE got real goofy with
it's BOF and EOF markers.

Well The first and last controls work properly but using them when I open the table doesn't change how the previous and next buttons work.  

Also whats really weird is the pause I experience on the last next is dependent on the type of query I do.  For example if I'm sorting through records generated by the query
Select * From TableName Where Value between '000' and '999' I get no pause on the last next hit.
but if the query looks like
Select * From TableName Where Value like '0%'
I'll get a pause when I'm on the last record and hit next.

I don't know if that helps or makes it more confusing.

That is not what I meant.

I meant something like this:

Query1.DisableControls;
Query1.Open;
Query1.Last;
Query1.First;
Query1.EnableControls;
