LG VX-4500

Was wondering if anyone else was having this problem. I synced a picture to my 4500. I is in my "graphics" folder, when I set it as wallpaper, the handset indicates that the pic was set as wallpaper, but when I clear out of the menu I have the wallpaper I started with??

The pic works with "contacts" but not on the wallpaper setting. I am using Datapilot to sync the phone with my pc

Thanks for you time
