VDJ Mix Lab V.3.1 skin doesn't fit screen
The reason for this is that your screen resolution is too small. It requires a minimum of 1280 x 800 resolution which is native widescreen for many 14", 15" laptops. Any 4:3 aspect LCD or CRT should also support this but you need to set resolution at the minimum to 1280 x 1024 which can be done by right clicking at the desktop, going to properties and then Display and changing the slider there.
If your monitor doesn't go any higher and it still doesn't show the whole picture, then either A - Get a new monitor that does, or you can click the Maximize button next to the X button on the very top right to stretch it to fit your screen but it'll be in a wonky looking aspect ratio.
