Question
The cursor within Model Space is very 'juttery', as if it is working to a 'random' grid. I have no grid or snap turned on. This problem is really hindering my work, as it takes an age to select the line etc. that I want.
I don't have a problem on the menus or the paper space or on any other program.
I'm a CAD operator for an architectural practice for 4 years, currently using AutoCAD 2004.  

Answer
Hi --
Sorry, I just have a minute right now, but let's get started,  try to sluth it out, and you can write back if still needing help, cool?  I dont even have time to open AutoCAD right now, must go from memory.

....if you dont have snap turned on (the symptom you describe imitates snaps being on, I truly doubt it is random, not in a grid pattern)
1-- my first thought is to hope this is on just one drawing with outside content, or an xref.
2-- since you are on 2004 and mention menus (rather than tool palettes), my inner Sherlock wants to think that, in clinging to old methods, you might have some old customizaton, LISP, etc, gone wrong.
3 -- you should go to OPTIONS, and look at the selection settings and user preferences (I am on 2007, forget if they have changed) -- it is poccible that  a setting has changed on its own -- happens -- mess with them a bit.

Barring finding an easy answer, I would do a repair install via Control Panel, or pull it and install again WITHOUT any customization, to see what you get.
Hope this helps.
