fg: No current job.

dear all,

I had a strange thing happening today:

[drum:~] g% fg
fg: No current job.

[drum:~] g% ps
PID TT STAT TIME COMMAND
9350 std Ss 0:00.57 -tcsh (tcsh)
9352 std S 0:00.78 tail -f /var/log/exim_mainlog

[drum:~] g% fg
tail -f /var/log/exim_mainlog

that job had been put in the background using bg (this is essential, a stopped job is properly fg-ed). I can reproduce it now on two machines, I did not notice it before... it looks like fg only works after the ps command has been issued. It also works if I give the job number explicitly (this is another machine):

[ti:~] g% fg
fg: No current job.
[ti:~] g% jobs
[1] Running tail -f /var/log/exim_mainlog
[ti:~] g% fg
fg: No current job.
[ti:~] g% fg [1]
tail -f /var/log/exim_mainlog


Am I overlooking something?
This is on a 10.2.2 and 10.2.6 machine.

Thanks

Giuliano
