In the newly released 2.2rc1 on Mac (latest OS) open two documents in two windows. Select the frontmost and select View > Hidden and the document in the background. LyX will shift focus to the background window, but (in contrast to 2.1) not raise it to the foreground. Is this intended? (As a sidenote, the numbering of tabs in the menu starts from 0. I guess this is due to C+ numbering? Should perhaps be changed to starting from 1?)
Regardless 2.2 is fantastic. The only negative thing I can say about it is that it gets worse and worse for me when I have to use MS Word… All the best! Anders
