Bluebeam® Revu® 2018.3 and above
While working in a Studio Session, a dialog appears, saying:
Please wait… A critical operation is taking longer than expected. This dialog will close when the operation completes.
All you need to do is wait for the server to complete the process; the dialog will close when all current activity is processed.
Why Did This Happen?
Too much Session activity can overwhelm Revu. This dialog was introduced in Revu 2018.3 to ensure that every action reaches every attendee before anything new is added.
