There are several places a kernel can be referenced from. If you have a Seaside application then you have to remove it from the config interface. Moreover you have to remove it from the collection returned by "MAKernel instances". Then it should go away, with all its content, at the next garbage-collect. The pages are stored in the i-var 'root' within the kernel instance. You might want to inspect/explore the model to see how it is connected: kernel explore Lukas -- Lukas Renggli http://www.lukas-renggli.ch
