autorun script on login

[Jonathan Hartje]

Joseph and Mark,
    Thanks again. The .xsession did the trick! I read the info Joseph 
pointed me to; However, I'm now in the same situation but the reverse 
timing. Is there an equivalent file which gets sourced on logout? I'll 
need to reset the software on logout so the next user that comes along 
gets a fresh runtime. I'm half way there.. Thanks.

Jonathan
