It's not well known, but you can create a screenshot from the content of a Filemaker window when you use the scriptstep "Copy()" without parameter.
The screenshot will then be stored in the clipboard so you can paste it back into a container field.
It' sometime useful to create a sceenshot of a preview window and put it into a global container field to show the user what he will get.
It works in Filemaker Pro (even in 12) since a long time, in Filemaker Go this does not work.
Any ideas or just a missing feature of go?
