queXF 1.13.2 has been released today on Sourceforge
A bug with downloading data on some browsers has been fixed. Definition of bounding boxes is now set by using portions of the page instead of each corner of the box.
To upgrade (from queXF 1.13.0 or 1.13.1):
1. Backup config.inc.php (copy to config.inc.php.bak)
2. Extract the new package over your existing installation
3. Copy your config.inc.php.bak file over the extracted config file
