The dialog box shown in the attachment (screen_skype.bmp) always appears while I'm making a SkypeOut call. It disappears automatically when it rings the first time. Any idea where this is coming from? And what it means?

Which version windows are you using?

And which Skype build?

Does it happens always?

Does Skype2Skype calling work well?

Sorry guys, found the reason for it myself: It's a piece of software called "Preispiraten" which is a tool to search best prices and it comes with a Skype integration. Not sure what it does by showing that dialog box but at least it doesn't disturb Skype, it's only that it shows that window.
