Stick Software has announced version 1.4 of Jiggler
(http://www.sticksoftware.com/software/Jiggler.html), a freeware
utility for Mac OS X. The new version is compatible with Mac OS X
10.6 (“Snow Leopard”).
Jiggler keeps your Mac awake through those lengthy tasks when it
would rather fall asleep, by jiggling your mouse periodically. This
means no more having to open System Preferences to change your sleep
time and your screensaver delay, only to have to change them back
again at the end.
Jiggler is Universal Binary, so runs natively on both PowerPC and
Intel Macs. It joins Stick Software products such as PhotoReviewer,
Eyeballs, Trisection, Fracture, BigFoot, Measles, Aquatint and
Constrictor.
