hi Richard! do you mean the field was not recognized, no symbols in it? or you draw a field in the image and now want to drag&drop it not to type symbols manually?
Richard, the pic is not showing, but I think what you mean is "rubberband" mode - when you outline a piece of text or just click on a word and it populates into the field. Am I right? It is possible, however this functionality was enhanced along the maintenance releases, so depending on your FlexiCapture release, it may work differently.
Most likely, in default mode when you outline some text on the image, the program will offer you to select a field where the information should go, and once you choose the field, it OCRs the text into the field. You can simplify this process a bit by enabling "Use text from cache" checkmark in Document Definition properties. In this case, the program will use already prepared text and populate it automatically into the field where the focus is. However, if the field already contains a value, you will need to delete its region first before populating a new value.
