Problem with 4.0.5 here as well Rated 4 out of 5 stars
Problem occurred when creating a new short-cut. FVD-SD would spin forever, thus no link performed. Even after re-running Firefox, still spinning. Moved back to 4.0.3 and no problem then.
Needs obviously a slight update, no big problem. Remains the best speed dialer IMO (even with its search engine, disabled!)
