Please openi a new Case for this issue: https://support.ptc.com/appserver/cs/case/case_logger.jsp
Opened one March 30th.....
I received some feedback from PTC...Below is what is needed for them to investigate. My system does not actually crash when I notice my figures have disappeared. I usually notice my figures are messed up after opening the file on any given day. If anyone is able to pull this off, it might help PTC correct what is happening.
We recently upgraded to Windows 10, and thus re-installed Illustrate 3.1. So far, all of the images are displaying correctly for each user. I'll be monitoring this to make sure if they change their libraries etc, how that might affect the display. I know that upgrading may not be an option for others, but it seems to have fixed it on our end.
Thank you for sharing that. I don't think upgrading is an option right now for us, but that is good to know. And yes, please keep us updated.
