I use Firefox and Gmail to basically manage my life. I also use the Gmail notifier. What I don't use is Internet Explorer. However last week someone other than me needed to use my computer to check their Gmail. Because they're weird they used Internet Explorer to do it. After their login activity my Gmail notifier starting telling me when the other person received new mail, even though my login information was stored by the notifier. I couldn't figure it out. A little research led to a terribly annoying bug with the Gmail notifier. The person hadn't logged out of Gmail and instead had just closed the Internet Explorer browser window. For some strange, annoying and potentially dangerous reason the Gmail notifier remembers whoever was last logged into Gmail through Internet Explorer, even if that login is different from the login put into the Gmail notifier itself. So the problem was easily enough fixed by longing onto my own Gmail account through Internet Explorer but it was rather annoying. I only point this out because I didn't find this information that easily when I started looking for an explanation and most of the examples of this occuring happened to people using Macs and the Camino browser. This was an all PC all Internet Explorer incident so I thought it might be helpful to share.
