I have three main computers I use daily: an ancient HP running Windows XP, an iMac G4 "FlowerPot" running Debian "Squeeze" and XFCE, and a Lenovo Thinkpad z61e running Xubuntu 9.04 "Jaunty Jackalope;" each is running the most recent version of stable Firefox. On both the old HP and the Lenovo, LastPass works flawlessly. On the iMac, though, it will not let me login unless I choose the on-screen keyboard option to supply the username and password.
Any ideas what the problem could be?
Thanks, in-advance, for your help.
