I use dual monitor for work and I prefer to have the editor on my main screen while the rest of eclipse in my laptop monitor.
However, when I open a new file, that is. I open a file with Cmd-Shift-R, files are opened in my laptop monitor as opposed to the editor that I dragged to my main screen.
I find this mildly annoying. Any ideas?
Are using the Window -> New Window feature? In that case it depends on which window you're working on at the time you press Ctrl+Shift+R.
However, if you're streching only one Eclipse window along both monitors, then the Open Resource dialog will be opened in your "monitor number 1" (and that depends on your graphic configuration: Laptop+Main or Main+Laptop).
