Running Atom 1.0.2 on OS X 10.11 Beta (15A216g) “El Capitan”
I use the standard File -> Open… menu item and the file picker appears. However, when I select any file or folder, neither the Cancel nor the Open buttons work and I have to force quit the app because I cannot dismiss the dialog. The buttons appear to be disabled, even when a file or folder is selected. Opening a file or folder with the command line tools (e.g., “atom ~/go/src”) works as expected.
Is this a known issue, or is this some weirdness unique to me?
