Thanks to all you helpers!

The method you decibed is descibed in the booklet which came with the
program, but:

This doesn't work here on my machine :(
[WinXP Pro, Guide8, the updated version]

1) I right-clicked on the first object and clicked "OK"
2) I right-clicked on the second object and clicked "OK"
3) Then I pressed the "Insert" button, but nothing happens at all :(

I have a german keyboard, and I proofed the insert button which is
over the delete button (in German: "Einfg").

For the next time I checked the insert button at the nummber-pad
(usually on the "0" on german keyboards), but this did not work, too.

So, I switched to the English surface of the program, => no effect

So, what to do else? Maybe the "Insert" button on the English keyboard
is another one?

thanks,
