Major Blender 2.49 Problem

Okay so i will be in the middle of working on modelling something or some other task in blender and usually when i get about half way through it stops letting me add meshes and the cursor won’t show up this has happened to me on at least five projects now and for no apparent reason any help would be appreciated.

Make sure your 3d curser is not out of view. Objects are added to your scene at its location. The new mesh would have been added and visible in the outliner but it will be outside of the 3d view clipping distance.To reset at the grid origin use Shift+C


that seemed to fix it thank you
