This happens every once in a while. This stupid box pops up on my desk top. It looks like it might be a dialogue box, but it is blank. The only way I can get rid of it is to shut down different applications. I think it might be related to contacts. It happens rarely, but when it does it is annoying because I don't know why it happened and then I have to try to remember which application it is that I have to shut down. So I go through a few, finally get the right one and then forget about it until it accidentally pops up a month later or a few weeks later. Here is a picture of the box... Does anyone know where it is from, so I stop making it pop up. Is there a quick way to shut it down without shutting down an app?
