Identity Safe auto-fill stops without warning, comes back on reboot

I have been having an issue where the N360-Identity Safe auto-fill stops working and often won't begin working again until I reboot. The password box fails to appear (I have all my logins password protected) when I go to a known page and even though the toolbar remains present and the drop-downs still open, it won't fill in the info after clicking the identity. There is no error message of any kind. This appears to happen in both I.E. and Firefox. It will sometimes begin working if I close the vault and reopen it. Sometimes I have to close and restart the browser after closing the vault. Other times I can't get it to work without reboot my machine.

I am running a Dell Alienware laptop with Windows 7 Ultimate, IE10 and Firefox 20 with all the latest updates.
