Diigo

Diigo is an online collaboration tool for learning. Learners share there online bookmarks with the community and attach annotation to show their understanding of the text.

Problem : When I install Diigo on my IE browser, the entire browser hangs. After several failed attempts, I uninstalled the programme. Fortunately, my IE browser is back to normal again. Need to find out from other users if they face similar issues with Diigo.
