Window overlay bugged

Basically when I open pop-up windows like Soundboard or even settings, or Client connection, the open window is not viewable superimposed on top of the client window in any way and the client window is always superimposed on all windows, including open windows of the computer in general that have nothing to do with TeamSpeak. This is very annoying since every open TeamSpeak window as mentioned above always have to drag where the client window is not present.
