Description of problem:

Hitting enter before the dialog pops up sends the event anyway and the dialog
sits for a few seconds before it allows you to enter a new password

How reproducible:

Always

Steps to Reproduce:
1. Lock the screen
2. hit enter
  
Actual results:

Dialog blocks for a few seconds before you can enter another password

Expected results:

Key events should work the same as in Xscreensaver.  The first enter is ignored
and just brings up the dialog if it is not showing.  All other keystrokes are
valid even if the dialog is hidden.  An enter after any other keystroke should
also be valid.

Additional Info:

The first space is also invalid.  I still have Xscreensaver on my desktop if you
want to take a look.
