Reverse Draw add in Sculpt mode

I following the Essensial Blender Chapter 5. I did this once and decided to do it again for a bit training. When I now doing the Draw add in sculpt mode it push the surface down insted of lifting it in LMB drag. I have to do a shift LMB to get it this time around.
I only have saved and closed blender and started it next day and started with a new project. But now it looks like the buttons is reversed.
Has someone any idea of what happend here ?
I have 2.48a and is new to blender.

Since no one had ansvered yet, I started searching. found one called “sculpt bug” and in here was the solution.
