Well, it's a problem with the "Look-and-Feel" setting, which I'd suggest you change, except the place to change it is inside the application, which won't open. Under Unix platforms, you could change that by editing the .openrio/jempegrc in your home directory, but I don't know where that would exist under Windows. The registry, maybe? Nope. Looks like "C:\Documents and Settings\<username>\.openrio\jempegrc". Open it with a text editor (like Notepad) and find the "jempeg.lookAndFeel" setting and change it (from "system"?) to "metal". Then try restarting it.
