Hello.  I am running the latest version of Photo Mechanic (4.4.3.2) on a Windows XP SP2 desktop.  As part of an assignment, I took approximately 400 .NEF shots on a Nikon D70 for a church photo directory.  I used PM to narrow the shots down to 110 keepers, and then applied a soft crop to each of the 110.  
The next step was going to be to applying the custom crop and save them as JPEGs at an appropriate resolution.  However, when I do <file> <save as> I get an error message “none of the selected files can be saved at high resolution.”  This seems odd, given that I can send them to myself via email and both the crop and the JPEG conversion works as expected.
Can anyone help me? 
Thanks!
Michael
