Facetime Active Call window can't be moved
After upgrade to the latest iOS, the active call window of FaceTime can't me moved by mouse ...
MacBook Pro (15-inch Early 2011), OS X Mavericks (10.9)
Actually, we've noticed this problem since we upgraded to High Sierra, the problem seemed to be not so important in the beginning but then it became really very annoying so that would be great if Apple can hear Mac users and include in the next OS update this bug fix so Mac users again could drag and move facetime icon while calling.
We even wrote the blog post https://bombappromotion.com/facetime-calling-bug-high-sierra/ to attract the attention of Apple to this problem, even though it is not crucial but it turns the overall user experience into unpleasant one.
