The ExposureBiasValue has been fixed in version 4.4.1 in the Exif pane and in full screen mode when showing exif data. However, it is still showing -5.61434e+006 EV for an exposures of -0.33 or -0.67 EV in the box when hovering over a thumbnail. All the other display issues look to be fixed also. Thanks for the quick turnaround with this version.
