When exporting an image that already exists in the target directory, PL4 prompts for overwrite / unique names / cancel. There is some inconsistent behavior with overwrite.
I have an image with two virtual copies, master and _1. When I export master the first time, I get image_name_M. If I come back and make edits and export again, PL4 issues the overwrite prompt. I select overwrite and it goes and does its thing.
In the end though, I get another file, image_name_M-1. The file that was supposed to be overwritten is not overwritten at all.
Even weirder: When I export the image again (now two exports on disk), PL4 doesn’t issue the overwrite prompt at all – it simply assumes new image name, and creates an _M-2, an _M-3, _M-4, etc.
This may be happening with virtual copies only. I haven’t noticed it elsewhere.
This isn’t a big deal but it’s a bug I’ve never seen in five years of using PL.
