User Comments:
javydreamercsw: Dragging a button from the palette.

claus_ch: I have a simple maven-based test project having a JFrame and a TextArea (everything default). The crash happened, while draging a ComboBox onto a blank spot of the JPanel in Mantisse.

asenk: I made a lot of steps before this exception.
Posible steps to reproduce:
Create new J2SE project and crete new JFrame Form
--Drag a Radio Button from pallete to JFrame Form

Comment 2 Tomas Pavek 2011-09-22 10:01:36 UTC 
Cannot reproduce, but I think this can happen when the last mouse move event comes from the white area around the form but then the mouse pressed event is already in the area of the form. You move mouse too quickly! ;)

Fixed.
