Yes, you've to launch it every time WinAmp is started. You can use Ctrl+Shif+K keyboard shortcut to do that.
>I have updated to WinAmp 5.531 and I still have the same problem. I put the visualizer window on the upper right. But, whenever I start WinAmp, that particular window is not appearing. I always have to select Visualization from the menu.
