Maintidget

I have heard of this happening for a few people due to the size change of the widget. All you need to do is refresh the widget by first clicking on it, and using Command+R (note that this works to refresh any widget).

MacJanitor is not a viable substitute for Maintidget. I used MacJanitor for years. It was based on the old cron (pre-Tiger) implementation of OS X maintenance scripts. Maintidget is tied to the current launchd (Tiger, Leopard) implementation of OS X maintenance scripts. Back then, if you didn't leave the Mac on overnight, the scripts would not get run. That is no longer a problem in Leopard in most cases, and that leads to one of the advantages of Maintidget. Maintidget reports the last time the scripts were run. In most cases, this report will indicate that there is NO NEED for you to run them manually because they have been running on schedule anyway. MacJanitor does not report the last time the scripts run, so because you're flying blind, you'll probably waste time running the scripts more than necessary. I use Maintidget as a monitor first and a fixer second, and I find that I hardly ever have to press the button. MacJanitor is both outdated and lacks sufficient feedback.
