Same problem weird keyboard problem
As weird as it seems, I have the same exact problem.
I haven't been using Virtualbox for a short while and today it's impossible to login to my Windows XP guest since the password will not work. When trying to type in the username box, everything I type is converted to a number. I can type A it will display 1, press A again and now I get the number 2. Then any letter or number will bring me 3... and so on.
I'm guessing this could be a problem with a Windows update or something? I can't seem to see what else could be affected. I had the problem on version 3.2.8 of Virtualbox but i'm still having the same problem after updating to 3.2.10 a few minutes ago.
Here are my computers specs in case we find something in common :
Windows 7 x64 Home Premium (Host)
Windows XP SP3 (Guest)
Lenovo G560 Intel i7 Processor 4Gb RAM
PS: I just tried with another guest on the same machine (Linux Mint Debian) and I get the same problem
