[vtkusers] Reference İmage problem

[seyyah776 seyyah776]

this image syngo fastview opened vtk As the image is not opened yellow lines

wants to open up the image of dicom images in series that is, or fails to
fold <attempted to read or write protected memory. This is often an
indication that other memory is corrupt.> This problem disappears when the
image disappear series
please help me
