"Isn't a bug..."
Don, I wouldn't be the first one to say that sometimes your pedantic
hair-splitting can be quite tiresome.
a) I have opened a support ticket; however, this "bug" forum is, among
other things, to let others know about problems. Close your eyes and
pretend the forum is named "Issues".
b) Yes, I know Impression is a legacy product; Impression within Studio hangs, too.
c) You also told me not to post on Facebook as well and yet someone
replied that the Intel HD graphics issues have impacted thousands, if
not millions, of users.
Try not to be such a thread tyrant.
