Every once in a while, Dashboard can become a little too “buggy”. It will use up a lot of memory at times causing a widget not to work as well as it should be. When I browse the web and a page is having loading problems, I usually just click the refresh button and it fixes things up. Well, there isn’t exactly a refresh button for Dashboard, but by holding down the ⌘ (Command) and “R” keys, the widget will refresh itself. This is also a useful feature for a developer who is making a widget and wants to make sure it is working correctly.
