How can I change screen titles?

Hello,
I’m trying to make my first screen with ScreenMaker 5.12.2040.0 and I can’t change the screen title because it is blocked. (A padlock is showed and the properties are in grey)

I could see in SCM_ExampleProject that the titles are changed, but I can’t change them.

Any one could help me?
Thank you very much.

Hello,

You can change the title for every screen present in ScreenMaker.
You can click on the Screen for which the title needs to be changed from project treeview ( for example MainScreen).
On doing this “The ScreenMaker : Properties window” will show the screenForm control selected. The Text property of screenForm can be changed for displaying the appropriate title.

Thank You very much!
I did it on the wrong way!
