I am transitioning from a PC (SnagIt 12) environment to a Mac (SnagIt 4.1.4) environment. I am unable to open the PC-generated SnagIt images using the Mac-version of SnagIt. When in Mac, File > Open, PC-created are greyed out. I notice that the PC-version has an extension of .snag - and creating a sample Mac-version has an extension of .snagproj. It doesn't seem to be as simple as changing the extension from .snag to .snagproj! Am I able to open a PC-version and revise/save in Mac? If so, how can I use previous screenshots/images?
