I can reproduce the behaviour in CS5 and CS6 on Mac.
But as I consider this pretty much irrelevant functionality I doubt that Adobe will invest programming time in recreating the previous bahviour.
May I ask what you need it for?
Several work-arounds seem feasible; Actions, Scripts, saving as ai instead of eps …
I know. Scripts, Actions, Image Processor are very helpful and in use but as an sleazy guy from time to time I'm also using drag and drop of a few files and in this case I mentioned it and tried to get an answer about its facts. That's all. Thanks for your information about CS6 as I thought about tryin it with the new version. This is not the end of the world, isn't it?
Thanks for your reply.
Might be a good idea but I think you already nailed it: "I doubt that Adobe will invest programming time in recreating the previous behaviour." Worth a try anyhow.
