#121 No response function file is saved

[Anonymous]

When creating an HDR file using Custom Configuration | Use Calibration to find response curve | Save Response function to file = true | Save As (specify unique new file name in default folder)
There is no file saved. It is not saved in the directory, specified, the default directory, in my user profile, in the image source folder, or anywhere on any of mu hard disks (I searched for it). It is not in the recycle bin,
Using Windows 7 64 bit with Luminance 2.2.1
Security permissions are OK for this folder.
This function worked correctly with Luminance 2.0.2 and seems to have stopped working recently. I did not try this function with version 2.2.0 however.
This is a 100% repeatable problem. I can't save any response files with this program.
