<TITLE>Strange behavior between vtkBalloonWidget and vtkInteractorStyleTrackballCamera </TITLE>

<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Hi All,<BR>
I recently started using vtkBalloonWidget in my application and I noticed that if it is enabled, navigation with vtkInteractorStyleTrackballCamera continues until the mouse is released. <BR>
This occurs for any type of navigation, pan, rotation, zoom. However if the balloon widget is disabled, navigation only occurs if the mouse is pressed and moved (button press +mouse drag). <BR>
Is this the intended behavior? If so, which callback event should I check for to disable the balloon widget while navigation is occurring? I tried “LeftButtonPressEvent” but my callback wasn’t detected.<BR>
I’m using Java with vtk 5.2 and I’ve seen this behavior on Mac and WinXP 32.<BR>
