Rated 1 out of 5 stars

I installed then (with great difficulty) removed this, from a Vista system running Seamonkey.
I think the assorted conflicts are a combination of both Vista and Seamonkey idiosyncrasies - or more specifically it is not designed to work with them, thus causes multiple tier crashes.
Can be very frustrating trying to get rid of it. I needed 'roll-back', then re-install Seamonkey.

Not recommended for Seamonkey on Vista systems, unless you're a masochist!
