I generally never Shutdown my computer, I am using windows 7 on my desktop, and somehow after changing images for a while wally just gets stuck. It will try to get the picture but it cant, The taskbar icon has a right directing arrow on it, possibly saying its trying to get new image but it fails. The only option is to cancel it quit and restart wally.

I image source is on FTP locally. so nothing is saved on the host.
