Hi Wade

I'll try to provide a simple example as soon as possible.

A GLCanvas is not a panel, it extends Canvas. If I want to use a JInternalFrame, you can only add it to its container, the Frame whereas GLJPanel is a container. As a result, a dirty grey area appears under the JInternalFrame when you move it if it is in a Frame and this grey area cannot disappear whereas it works fine with the GLJPanel.
