潘冠敬 commented on PDFBOX-107:
----------------------------

hi,The reason of the viewer crashed  is the JFrame.setVisible(true) not blocked,so it will throw "IOException : handle is not useable",when you call the 
PDDocument.close() method. Because this is earlier called than PDFPagePanel.paint() method.The follows can fix the problem:
1.Use the model JDIalog replace the JFrame
2.call the PDDocument.close() after  PDFPagePanel.paint() every time.
