If your project involves multiple Show Controllers, ShowTouches, and you are in need to copy your panels from a Show Controller to another this would be the fastest and recommended method using the "Import" and "Save As" function.
In Winscript Live, open your script. Click "File", "Save As" and select .tca as the "Save As Type".
Once you save the .tca file, open your new script and select "Import" from the file menu.
Select the .tca file to import.
When prompted, select "Merge" option.
