I have been using i-Vault successfully for several months now - but 2 or 3 times, it gets into a state where it just will not fill forms on pages that are normally no problem. Reboot does not fix it! 
So far, the only method I have found to overcome this is to export the passwords, etc and save them (just in case), de-install and re-install.
After that it works! :SMLR
Is there anything else that could be done to fix this? Maybe a registry tweak or something. It is a pain having to re-install.
