I rely heavily on having pinned documents within a pinned program on the task bar. I.e. if I right click on the excel icon I would have a list of pinned, and then recent items. I no longer have my pinned icons and can't figure out how to add pinned items.
Last Monday we released a new DisplayFusion beta version (http://www.displayfusion.com/Download/Beta/) and this issue should be all fixed up. Please let us know if you run into any trouble after updating.
