[gl4java-usergroup] prog never returns from gljMakeCurrent()

[Combe, C. <C....@na...>]

hi, i've been trying different ways of swapping one type of GLCanvas in an
application for another. Here's the current problem - after removing a
GLAnimCanvas from the a JPanel and then adding it again, the program never
returns from the glj.gljMakeCurrent() method, it just fails silently. The
following bit of code prints "hello" and nothing else, and then the program
is frozen.

            System.out.println("hello");
            //Ensure GL is initialised correctly
            if (glj.gljMakeCurrent() == false)
                        {
                        System.out.print("whoops");
                        return;
                        }
            System.out.println("made it");  

any suggestions?
thanks,
