I'm guessing that's because I set Pardus to clean out my /tmp directory on closing, as per your previous advice to tame my runaway /tmp directory.
I do not think so as the new user doesn't have the problem.
And the /tmp directory is common to all users.
On my test computer I can not reproduce the problem whatever I do.
As far as I am concerned it's a once in a lifetime occurrence.
And the final solution can also be a re-installation.
