rdp background images

so i use RDP pretty often... and i have a background set on my desktop... one of those pretty nature scenes that has been included with vista... now when i login via RDP it starts to load that... VERY VERY slowly... which... is expected... once it finishes loading... it vanishes (yay!)
why is it even attempting to load it in the first place? and i know you can go in to the RDP properties for the connection and disable that stuff. but if thats the case why does it load it all, and then remove it? seems like a huge waste of time.
anyone else see this?
