I am not getting "delete" when I right click on a Diigolet highlight I made ... is this a current glitch? I cannot delete any highlight or note I have made.

This is really helpful -- thanks. And indeed -- I am desperate as a teacher for an online annotating tool, and the delay in timing with Diigolet (that you just helped me see) is going to be a hindrance to using it.

A first reload + re-presentation of Diigolet may give the false impression that only a few of your annotations were shared as requested. A later review should appear better.
