I have a paid account in Forms Central. According to the Help Notes, I should be able to right click an element and copy it and then right click on the form to paste. I am able to copy elements, but when I right click to paste, the command is not available.
I just figured this out. I opened Forms Central in Internet Explorer instead of Firefox (my usual browser). The function works in IE, but not in Firefox. Problem solved...
There is a known bug in Firefox where copy/paste doesn't work for Flash applications. It will work with Safari, IE and Chrome.
