FULL PRODUCT VERSION :
java version "1.6.0_02"
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
customer Windows XP [Version 5.1.2600]
A DESCRIPTION OF THE PROBLEM :
If you press the right mouse button on the slider track, the slider value changes. This is not Windows default behavior. One bad example: You want to open a context menu on the slider, and with the same click the value changes. The slider value should only change, if the left mouse button is pressed on the slider track. This could be solved by adding an if(e.getButton != MouseEvent.BUTTON3) to the TrackListener of BasicSliderUI.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JSlider value should not change when the right mouse button is clicked on the slider track.
