I'm not really sure what the problem is. On my work computer, as I don't have admin rights, I'm trying to use the Diigolet bookmark. However, whenever I try to highlight anything, this error appears by the Diigolet bar:
The number of highlighted non white space characters needs to be between 5 and 2000. Please select some text and try again.
Everything I've selected has been within that range; trying again doesn't yield any other result.
