Serious bug time!
Just upgraded via market, and now can't login to any profiles with numbers in the passwords from the enabled lock screen. To clarify, the numbers on the keyboard do not work via the lockscreen and neither does backspace.
Luckily for me I kept a guest profile with no password, and could use that to login and reset the other passwords.
I have had to remove all passwords as I can't uninstall without losing profiles. :(
Also, each profile auto upgraded so once you switch you get locked out....
version 1.3.4 rev 32 is the one I got upgraded to. Please fix!
