Sometimes, when i move the mouse over the editor (doing nothing else) or scrolling the map when holding the map scroll slider, i get this exception. I can't force it, it come at random. Anyone has a idea? exception occurred during event dispatching: java.lang.InternalError: getGraphics not implemented for this component at sun.awt.windows.WGraphics.createFromComponent(Native Method) at sun.awt.windows.WGraphics.<init>(Unknown Source) at sun.awt.windows.WComponentPeer.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at java.awt.Component.getGraphics(Unknown Source) at javax.swing.JComponent.getGraphics(Unknown Source) at javax.swing.JComponent._paintImmediately(Unknown Source) at javax.swing.JComponent.paintImmediately(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)
