Hi Steve Thank you very much for your advice, great support.
For second question I would like to specify. I have difficulties to handle the second screen. e.g. I have a large curved screen as a second screen that is great for video editing. Whenever I move the premier window to second screen and want to make full screen it jumps back to the first. I updated my version revcently and I had in mind that this bug was solved, but to my surprice it still doesn't work. I think this is a bit of a shame for a company like Adobe. I know it is first built for Mac but I think there are many Windows users as well with the same issue. Of course I can change the screen setting (e.g. on screen only) but I would like to use it as it is. I also would like to use the second smaller screen for other purpose during editing.
