I have installed the new DoppleViewer 1.5 on three machines, a G5 dual 2ghz tower, a G4 17 inch PB and a DualCore iMac - all with 10.4.7 and in all cases it crashes during loading.

As of 7/4/06 or so, DoppleViewer 1.4 now says:

"You have linked to, or downloaded an image from

National Weather Service radar images
are no longer available on these servers."

I hope DV is repaired soon - it's got a lot of wow factor when I show people my MacBook Pro's features.

As the previous reviewer noted, it would be great to have the option of loading animated loops to see the motion.

Still, a great Widget! Thanks, Swannman.

Sorry Charlie.

This is a neat widget but no more different than a webcam viewer. I went to the National weather service. I put in my City and pulled up the Short Range Reflectivity. I copied the Image address. I then pasted it into the SlothCam Widget. This sounds like no big deal but when I did this I realized that the SlothCam Widget was updating the images before the images on the National Weather Service website. I had one image that was available 6 minutes before it was available on the website.

This is no slight to DoppleViewer 1.4 or any other version. I just though people may be interested in this. Perhaps you could add when we want it to update. Otherwise I will be using my SlothCam to view this and alos in almost full screen.

Very cool widget. Its nice to have both this widget and the weather widget open for more advanced weather information. It has a limited number of cities, but the maps are quite large and include a lot of the surrounding area. It would be nice if this was a animated widget though, and you could actually view say the last hour or two, instead of just a single screen shot.

The latest version of this widget closes immediately after opening on my G5 iMac running OS 10.4.7. This happens every time I try to launch it.
