sorry, my enghlish not very well.
i have a problem about chat logs. i have 2 windows xp user logon. first user have admin rights, second is limited user. i use limited user's logon.  i have setup messenger plus live in limited user with admin rights. i have used "different run" - i think like this-  on mouse's right button for setup messenger + live.
first use, chat log run, very good. - i think it used with admin right. but i shut down pc then restart. then i cant use chat log in windows xp limitted user logon . now chat log doesn't run.
pls help. are there any registry option can i change for chat log? or another  answer for this problem.
