Dear All,

I am facing a strange problem with the user switcher in Fedora 7 and
can not seem to get the hang of it.

Let us say that I (User A) am busy with my work with many windows
open. Then my son (User B) wants to play games for say 30
minutes. Since I want to resume as soon as he is finished, I (A) do
not log out and use user switcher to log him (B) in. When he is done,
he logs out properly (user switcher is not used). Then the problem
occurs. The screen goes blank, where the screen lock for user A was
supposed to appear.

After some considerable period (n minutes), screen lock prompt for
user A appears. Just on a hunch, I changed screen saver timeout for
user A, and it appears that n has got something to do with this, but I
am not sure.

Could you please tell me what is happening? Is it a bug? A feature? Or
I am missing something?

Thanks in advance.

I am also puting below the contents of .xsession-errors if it is of
any interest.

I've had the same problem in other distros. I've found that sometimes it helps
to press a key (and I usually use Escape) or move the mouse or both ..
