Help with: Wi-fi synching and Automatic Pictures Update

[throgs]

For some reason one of the best of features of the iPhone 4s is not consistently working for me.

When I plug in my iPhone to the wall charger, I was under the belief it would automatically on the "photo stream" folder update with my latest photos.
It used to, but does not anymore. I have to manually add them by copying them from the iPhone on "my computer"

When I plug the iPhone directly into the PC, I still have to manually add.

If I want to synch and update music; I have to direct connect into my computer.

I have Windows Vista, so is it possible some extension is unchecked and if not what is the solution?
It's very annoying that something I paid for is not working; this is supposed to save time but wirelessly synching music and photos.
Thanks.

Got a message from MS Windows:

"ApplePhotoStreams.exe has stopped working"
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

Are there certain startup programs I need; as I have apple mobile device, bonjour service, iPod service.
