Comment 20 for bug 1244397

Johnny Wu's workaround does not work if you have more than 2 displays.

I'm trying this on a MBP with 2 external displays, one on display port, the other on HDMI.

If I open Inkscape via a new window, it opens on the root screen. As soon as I try to open an existing SVG, that window opens off screen, and I can't seem to move it anywhere, even with Mission Control. It just keeps moving back off-screen.

I'm running 10.12.4 (Sierra) using 0.91.
