Our school has 800 user accounts. Occasionally a user will encounter the
following dialog when launching Firefox...
"Close Firefox: A copy of Firefox is already open. Only one copy of Firefox
can be open at a time."
This is a documented issue at the following web site, and relates to an
invisible file ".parentlock" not being deleted when Firefox quits (or
unexpectedly quits). http://kb.MozillaZine.org/Profile_in_use
Does anyone care to share how they resolve this issue for students in their
school?
I have a script installed on all the machines in /Library/Scripts called
fix_firefox.command
Since I've added /Library/Scripts to the path (via /etc/profile) they can
either type in fix_firefox.command in a terminal window or use Finder to
navigate to that directory and double click it (this is in 10.4).
The script is a couple of find statements. In theory, one person
could have multiple profiles an if they wanted one locked and the other
fixed, well this would cause an issue. This also fixes Thunderbird (which
I've only seen break this way once).

It is by the beans of Java the thoughts acquire speed,
