Hi there,
Continuation of this thread.

Just wanted to comment the old way of launching the little slideshow app by simply double-clicking any thumbnail attachment was great!

But now, if the post just contains pics as basic attachments, double-clicking the pic in the eml almost freezes the system before a "How do you want to open this file" popup appears. So if the eml has twenty pics, one has to negotiate the same popup twenty times.

It would be helpful if the "View slideshow" button was not available if it doesn't function for these types of attachments.

There was a fixit way back here- would that help anything now?

Thanks for reading!
