Hi JJMAck, Thanks for responding so quickly. I am using an iMac with OS X Yosemite (10.10.15). It is Adobe Photoshop 2017. Its not really an error message or a problem, it seems to be a software feature. Below is an example of what I mean. I cant show you the actual files as its work-based, i.e. confidential. However, its not a file-specific problem, e.g. like a file error, but rather something Adobe has created. Its also not a layers issue as these are flat jpgs, not large in size either, nor is it a CMYK or RGB thing. I have attached a step by step on what occurs. 1. I open up an existing jpg 2. I make a simple crop 3. I go "Command S" and get a pop up box where Photoshop wants to default it as a psd file.4. If I then select the "jpg" format it then wants to save it as a "copy". All I want to do is save my open jpg with the new alteration. In my mind it should be a simple enough command, i.e. crop, save and close as you would if you were making a text change to a document. Hope that makes sense. thanks for your help.
