Did you look up "exists" in the dictionary? That also refers you to 
"there is" operator in the "see also" section.

If you lock messages as well as locking the screen, you probably won't 
need to show a loading dialog. The display and update of the dialog is 
likely to take longer than just creating the fields. I can create 500 
fields in under 2 milliseconds.
