I've installed it and I have a screen with a little box with 3 options of analysing bookmarks.

There are three balls rippling back and fore from small to large which I presume is telling me summat's happening, but - nothing's happening.

Half an hour now and Zero Bookmarks in the box on the screen.

Am I missing something ?

There IS also a box in which the words "Check bookmarks" appears. It is greyed out and cannot be selected.
