Preview stores changes without cmd-s
Hi,
I am using Preview version 5.5.2 on Mac OS 10.7.4.
1- When I carry out changes on a JPG file, Preview automatically saves the changes to the ORIGINAL FILE! I never press cmd-s or do anything else to save the changes as I want to store the resulting picture in a new file. The original should NEVER be changes! Obviously I am doing something wrong!
2- There is no "Save as" menu item in the File menu. Why? Instead there is "Export ..." that I don't really understand. What was wrong with "Save as"? The rest of the world is using "Save as". So why did Apple change this menu item to something different?
3- When I export a export a file, it is changed WITHOUT file extension even when you specify the file type like JPEG or PNG. So instead of storing the file as "somename.jpg", it simply stores it as "somename"! Is this again another change of Apple because they think it is better to do so for the user?
PLEASE: Never touch a running system!
Preview was good enough previously. This modernisation is just a pain!
Is there anyway to fix these issues in Preview?
Thanks
G.
