Unlike Ksnapshot, there is no option to save an image to any disk location other than the user's Pictures directory. I don't use that directory. In fact I don't even have it. Please add the standard file save dialog, including "Save as" option.
Please see my question in Bug 394500.
No answer, closing as WORKSFORME. Perhaps the global shortcut (which saves directly) was used instead of opening Spectacle as an app.
After a desktop upgrade, this function works fine. Thanks.
