Logging in?

Well among the two new scripts I have downloaded that allow me to Login using my Username and pass through the script. Once I get to the screen it clicks the Username box then the Password and clicks Login although it does not type anything.(Also thought through whenever i open the scar window just to test it it starts to type what was needed)

Could this be a problem with vista?
I have the latest SRL and the newest scar version.
