Okay, all derailing aside now.
Guess I wasn't clear I want to know how to make it not compleat an action when the left mouse button is pressed.
If you want to perform a specific action, you need to make an event in your event sheet that defines that action.
Have you read the tutorial? It goes into some of the basics of creating events.
If you have't added the Mouse & Keyboard object to your layout, you won't be able to make events with the mouse. So be sure to add that.
Other than that, read the tutorial on how to make basic events.
