      Description


      In Win 98 and Win ME, severe performance degradation is noticed when dragged over target panel, using Robot.

      The speed at which object is dragged is greatly reduced, on Target Panel, compared to Source Panel.

      Attached here with is DnDTest.java and TrasnferableObject.java
      Compile and Run DnDTest

      The Robot drags the list from Red Source Panel to Green Target Panel.

      When the robot crosses Source Panel and enters Target Panel, the rate at which its dragged is greatly reduced.

      The time taken for to travel half the distance of the panel is displayed on top.
      Compare both the values, in Win 98 and Win ME, there will be large difference in the values

      When I tested in Win 98 ....

      Time taken in Source Panel is 3 Seconds
      Time taken in Target Panel is 33 Seconds
