I have a set of container fields that users regularly drop files into and export from - the latter using a right click on the mouse and "Export field contents'. Unless I'm missing something the FM way of indicating the container is active, and thus ready for receving or exporting a file,appears to be to just darken the thin border which isn't much of a visual clue. So I'm trying to devise a simple and fast acting method to indicate to the user that they're in the correct, ie. active, cnt field and which works with either a left or right click into the field. Any suggestions?
