I have just tried to post to this community using IE9 and clicking on the Topic button using IE9 as my browser the button does nothing, however, it work's OK when using Chrome.
When using IE9 as my browser and creating a new "List" from the "My Library page" then going to a web page to add to my newly created list and selecting the "Bookmark" button on the Diigo Toolbar the bookmark option window opens OK, however, selecting add to list then more options the add to list shows the drop down menue but the newly created list does not appear with the options available in this drop down menu.
All seams to be working now for some reason. Thanks.
