Zeiss -- Stereo Investigator is crashing

Users have been having numerous Stereo Investigator crashes lately, and we don't yet know the reason. I personally have been experiencing frequent Ludl stage errors, but it has not really impeded my work much. Two users who are doing Optical Fractionators have been struggling to get anything done. Tonight, I came to check it out and found that using the Optical Fractionator without the workflow appeared to work, and that starting a new file from my own account (rather than the user's account) worked alright, but we couldn't get the workflow to not crash when she was logged in and using her data file. I'll call MBF tomorrow to see if they have any insight.
