Hi All, I am having a problem with IViewCursors.
I am trying to detect if there is another element or not, so I can activate a next and previous button. In short I can't watch or listen to events when the cursor changes in my view, as when I do, the current and the bookmark (which should be the current) are out of sync. The bookmark seems to be one behind. This code should show you the problem.
