What happened to the Show GUI (popup)?

In the Gui Editor Help (F1) it talks about a Show GUI (popup) that let's you "choose a screen to edit from all loaded guis".

My toolbar doesn't have a Show GUI (popup). How can I activate this.

I'm trying to edit my playGui.gui, but everytime I run the Gui Editor, it brings up the EditorGui. If I try to save this as the playGui.gui, it doesn't save my changes.

Remember, I'm a total newbie, so I need things explained to me like a small child.

Thanks!

PS, just to elaborate...

I'm trying to convert the ScoreCounter from the gettingStarted.pdf to a GoldCounter. Everything should work, but naturally it hangs on loading. Well, sometimes it hangs on loading objects, sometimes it while lighting mission.

But if I cancel, and go into the World Editor, and load GameOneMission.mis, it loads. But without the Score Counter [GuiTextCtrl]. Did I somehow save the Gui wrong?

I tried again. It IS a problem with my Gui. From the World Editor, I load GameOneMission.mis, which loads without any problems. Then I toggle to Gui Editor (F10) and add my GuiTextCtrl for GoldCounter, make all the needed changes, and save as playGui.gui and toggle back to World Editor. So far so good. When I collide the blue guy with the goldNugget, the nugget disappears and my Gold: 0 becomes Gold: 1.


It works correctly at this point, but when I exit and try again from the Start button, it hangs. If I go back into the World Editor and load GameOneMission.mis, my GoldCounter GuiTextCtrl isn't there anymore. If I replace it, it works until I exit and click the start button. Why? I don't understand. I clicked APPLY, and saved the Gui as playGui.gui. Why didn't it save the changes?

Thanks again...
