Why does Picasa remove the processing when I load RAW files?

And, how can you preserve the camera processing settings when you upload the RAW photos into Picasa?

I'm using a Nikon D90, so I know the files are compatible, but when I open them with Picasa, I see the processed image the camera saves for a few seconds, and then it removes all the processing.

It seems like the ideal situation for Picasa would be to preserve the processing from the camera, and edit the RAW files like it was a JPEG. Then, since you can't really edit RAW files in Picasa, you could then still use a more advanced file.

Is there any way to do this, or any other softwares that give you the quick editing and sharing capabilities with RAW files, but preserve the camera processing?
