'''Re-starting the Quick-Look software'''
* There is a memory leak in the Quick-Look software which causes its memory consumption to grow larger each time a new spectrum is loaded. To work around this, please restart the quick-look software once daily, or more often if required. Open a terminal and issue the command
ps aux | grep qlspupnicql-spupnic
* If nothing is returned, then the quick-look software is not running. If one or more lines are returned, then they describe running instances of the quick-look software.
* Each running process should be terminated before a new instance of the Quick-Look software is started.
