Views keeps crashing when I change setting
It is jquery version issue. Views is not crashing, It is returning json response which  Drupal is not handling properly due to jquery version issue. If you are using jquery_update module. Change the jquery version to 1.5 or older. If not; use this module. Latest jquery_update module allow you to set different jquery version for administrator pages and actual site nodes. Set the jquery version 1.5 or older for administrator pages and higher for actual site nodes if needed.
