CVS edit problem

[Jiri Pechanec]

Hi,

I need an urgent help. Our group consist of  four developers. We are using
CVS. We used cvs edit command. It worked ok.

Now, for unknown reason, one persone can cvs edit file. Another person can
cvs edit file too without any error message. But when this person tries
command cvs editors, he can looks that he has locked file with no name,
first column is empty.

Any ideas please?
