Install software on your machine and you'll expect it has been through
rigorous internal testing so there are few problems after installation. Not
always so, particularly when the majority of software is produced by individual
developers.
As software is updated regularly, issues involving erratic software
performance can simply be down to the particular version of the application you
may be using. Even release software can include bugs and problems in early
stages, with older versions of software may not be stable on a newer operating
system.
SUMo (Software Update Monitor) is designed to help keep applications
up-to-date. The simple update reminders that are integral to many applications
are great if you use the software regularly, but SUMo will alert you when
updates are available, even if you are not using a particular program.
