Drag and Drop and registering mouse events on components at same time

Hi, i need to write my custom TranferHandler for transfering images between JLabels and register mouseEvents on JPanel where r these JLabels in. But it seems that when exportAsDrag from mouseListener on JLabel is invoked, no other mouse events cant be registered on any components and/or mouseListeners until Drag is finished... Why is that and how to do so?
