[IGSTK-Users] Segmentation fault + GLXBadDrawable

["Özgür Güler"]

Hi Patrick Cheng,

the error remains unfortunately adding the lines below

  this->DisplayAxial->RequestRemoveObject( m_ImageRepresentationAxial );
  this->DisplaySagittal->RequestRemoveObject( m_ImageRepresentationSagittal );
  this->DisplayCoronal->RequestRemoveObject( m_ImageRepresentationCoronal );
  this->Display3D->RequestRemoveObject( m_ImageRepresentationAxial3D );
  this->Display3D->RequestRemoveObject( m_ImageRepresentationSagittal3D );
  this->Display3D->RequestRemoveObject( m_ImageRepresentationCoronal3D );

thx
Özgür
