How does optional software work? From what I can see it does not to see if I have it anything installed. I have Google Chrome 15 installed what is the latest but a test version. Opera that is the next version that is in testing. Thunderbird the next version that is in beta testing. Is it just going to download the latest release and install it over the test version I have installed? Would it be better for it to check first to see what you have installed then download and install. Thanks and keep up the great work.
