windows 7 sleep mode

Hi all,

Can anyone help me find out why the space-bar on my keyboard will open up the first profile in the list in Windows 7, instead of just waking up the computer after it goes to sleep? I could just tap the keyboard in XP to get it to wake up, but now, if I touch the keyboard to wake it, it goes right to the first profile. I have looked in power management but don't see anything related to which keys will do what. If I right-click on the mouse, It will wake the computer and take me to the profile login screen, Which is where I want to be.

Thanks in advance for any help. :confused
