I use the new Pixinsigh on a Macbook Pro 13" NON retina (1280x800), and the new UI keeps expanding beyond the edge of the screen. When it starts it looks fine (see image 1 bellow),but as soon as I load anything it automatically expands beyond the edge and can't be resized (see image 2 bellow).
See the
Video Hardware section of the System Requirements page. Your screen resolution is well below the reasonable minimum requirements. You'll need to reorganize and/or close tool bars to reduce the requirements in horizontal resolution. You may also need to close some explorer windows, or move them to the right side. Working in full screen mode is also a good idea to maximize available space, as well as using a non-native menu bar to increase the dimensions of maximized images. All of these customizations will help you using PixInsight on a very small screen.
Also in the previous version I could start some processing and switch to another desktop (space). Now durring the processing, the open window (like STF or the current process) keeps poping beck to the front and take over the focus in my other desktop (spaces).
It is true that, although I have tried to avoid it, the PixInsight main window is still being raised automatically by OS X when it finishes a running process. This should not happen because PixInsight is not trying to activate itself or stealth the keyboard focus, and in fact this does not happen on FreeBSD, Linux and Windows. This is a problem with Qt on OS X that I'll try to fix in the next version. So far we have had too many priorities to invest the required time to work on this issue.
Both of these issues are very annoying.
Annoyance is a relative concept. For example, both of these issues are relatively minor IMO, considering the amount of work behind this version of PixInsight. I am sorry for not being able to fulfill your expectations. Hopefully I'll be able at some point in the future.
