One important difference between our modified version and the original RFV is the way the focus window is set. In the original RFV, the focus window follows the movement of the mouse, while in our version, the user has to click in the desired area to set it.
If you wish to download the modified RFV and Replayer programs, the JAR program files are available here. Also available is the Java 2 source code, although this is not necessary to run the programs. There are also sample input files and images that can be downloaded that demonstrate the features of this version of the RFV. Alternatively, you can download all these files as a gziped tarred set of files from here.
Please refer to the User's Manual and Tutorial for information on running the RFV program.
