We have an instructor who consistently gets "timeouts" and loses work when grading documents in Crocodoc. He is viewing the document and then putting all of the comments in the comments box (due to a separate issue with Group Assignments and Crocodoc). I had not experienced any timeouts associated with Crocodoc, but I experimented today and found that around 50 minutes into a grading session I started getting this message
"Your Crocodoc session is expiring soon. Please reload the window to avoid losing any work". During my test session, I was only typing comments into the Comments box. Once I got that message, even though I completed the first comment and started a second, I started getting the popup warnings every few minutes.
Is there a specified time limit on Crocodoc sessions?
