When working with large table, java loads additional page of data 
unneeded and causes the application to freeze. 

When table navigation goes directly to the last row of data 
through <Shift TAB> key, the last page of data is loaded 
correctly. 

At the moment, <ALT> key is pressed to navigate the menu item 
on top, java loads all the pages of data unneeded. 
The unnecessary loading causes the application to pause. 
User should be able to navigate the menu item without 
delay any time when the application is running. 

Additional pages of data should not be loaded at this 
time as they are not requested through table navigation.
