Crossing window in 2004

Hello everyone
ACAD 2004, trying to select anything:
- click no. 1
- pan anywhere
- but WTF, first selection point, when it gets out of the screen,
"moves" as i pan, so it's always on the edge of screen.
Is there some system variable to force it to stay of the screen i.e.
where i first clicked?
Thanks in advance!
