Dorico crasches if backspace is pressed on the New Page tab when there are unsaved changes to the project. If there are no unsaved changes nothing happens when backspace is pressed.
- Make some change to the current file and do not save it.
- Open a new tab (both CTRL+T or the new tab button in the upper right corner works).
- Press backspace to make Dorico crash.
Windows 10, 64 bit
Unfortunately happened to me when I thought I had my browser in focus, causing my to lose several bars of work.
Edit: Corrected system specs.
