pre-load all project's forms before displaying startup form

I have a project that contains a few forms. Each form do a lot of processing in its load event, so when i navigate from one form to another, there is a delay before displaying it, while the code placed inside the load event executes. What i need to know is how could i go about making all the forms start when the startup form of the project starts, but without displaying them? In other words, is there a way to load all the forms in the background, so when i call form2.show() it is already loaded and it only becomes visible? Thank you!
