Hi,
the presence or otherwise of an ESS is not the issue.
Some screensets have an extra tab, some don't.
For example, I updated my Mach4 build on my machine only to find that the new wx4.set did not have a machine diagnostics tab,
so, I added a new tab and programmed it the way I wanted it. I tried copying that part of an existing screenset that had the page that I wanted
but did not have that much luck trying to do so. I'm sure is possible but I didn't invest enough time to work out how.
I just programmed the block of data I needed...took about three hours.
