So I have a weird behavior for anyone who would like to solve this
knundrum.  I have JTREE code, that when adding a child node to the root
node, works great on *nix and Mac OS X, however, fails on Windows.  The
code is:(in pseudo)
...
((DefaultMutableTreeNode)((JTree)comp).getModel().getRoot()).setAllowsChildren(true);
DefaultMutableTreeNode child = new DefaultMutableTreeNode("new");
((DefaultMutableTreeNode)((JTree)comp).getModel().getRoot()).add(child);
...
Now, if I run this on Windows it will return: an IllegalStateException:
node does not allow children...

Why is this?

Thanks in advance,
m2
