If you click on the top item of the tree (wxMach), you can add a page with the "green plus" toolbar button.
Hey guys, here is where I went awry.
Per Ger's quote (TP-Mach3 Example) in this case, you can see where the new Page shows up in the tree.
Where does this end up ? and how do you get to it in the .set ?
If you click on "notebook7", then hit the Add Page button, a new tab will be created in the notebook.
I'm guessing that this is what Gerry actually meant to say. ? ? ?
Clear as mud now
