I have version 18.104.22.168
I find that SP seems unable to distinguish between certain sites which use the standard Windows Authentication dialog for inputting credentials. For example, login info for my Netgear Router configuration page is stored in SP. Now, when I attempt login to www.zoneedit.com
(which uses the same kind of login dialog) SP suggests the 'admin' username for my Netgear router, and when I change it to the Zone Edit data, SP offers to change the Netgear account info. I cannot find a way around this.
I was also suffering from the same constant balloon notifications posted elsewhere so look forward to version 22.214.171.124!
