With Helicon Focus 6.3.0 Pro under Windows 7 Service Pack 1 I am now getting:

whenever I save a render. The saved file itself seems OK in photoshop, inputs and outputs are all 16-bit TIFF. I wasn't getting this message when I first installed HF 6.3, but it appears consistently now. Since the files seem to be OK consider this an advisory.
Thank you,
Don Craig
