EVALUATION That's because of javax.swing.plaf.basic.BasicButtonListener#mousePressed implementation. To support multiClickThreshhold there is the following code: if (lastTime != -1 && currentTime - lastTime < multiClickThreshhold) { shouldDiscardRelease = true; return; } If currentTime is in past that code denies click event. We could add "&& multiClickThreshhold > 0" in that if statement to fix the problem...
