Please add secure virtual keyboard + antithief function like in stickypassword http://www.youtube.com/watch?v=CyLCKosBEB4
now virtual keyboard from plugin is unsecure and caught by any weak keylogger.
If you have a key logger installed your data is already compromised. If you must use KeePass in this way you can enter the master password on a secure desktop - this will not prevent passwords entered into other applications being stolen.
Tools > Options > Security. Scroll to the bottom.
i reported before, i've got problem with language layouts on secure screen.
btw, link above very interesting option for people, who can't use secure screen.
