Hi Laurie
Another user (on another thread) has pointed out that the "enable multi-threaded processing" setting does not "stick" between runs of Excel.
Can I ask - when it crashed in preview had you re-started Excel since clearing the setting?
If you are not certain, please could I ask you to try once more, clearing the setting and then repeating the preview test?
