I have a form that will, upon users intevention, automatically bring up a second form.

What is more efficient:
Have the form2 load up as the form2 is needed or have both forms load together and set the visible properties of form2 to false until it is needed? (I am concenred about processor and memory usage.) -Note- It may be possible that form2 might not even be needed.

Your help is greatly appreciated,
Daniel Christie
