A DESCRIPTION OF THE PROBLEM :
When you quickly drag select over all rows in a JTable not
all rows are selected.

 
We have users who want to be able to quickly select all
rows using the mouse. (They are morally opposed to ctrl-A).
This behavior is driving them nuts.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Run SimpleTableDemo.java distributed with JDK 1.4.1
2.Click on the first row in the table.
3.Quickly drag select to the bottom finishing with the
mouse well below the edge of the table.
4. Not all rows are selected.



EXPECTED VERSUS ACTUAL BEHAVIOR :
I expect that all rows should be selected. In actuality
not all rows are selected. If we repeat the above procedure
*slowly* drag selecting, the result is that all rows are
selected.

 We have a group of users that is going nuts over this.
They need to be able to quickly select all rows with the
mouse.
