Every start produces:
"Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged."
Same as this: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=785691
This happens with the 0.36.3 from https://launchpad.net/~webupd8team and one I built myself (which is no surprise as it's a GTK issue...).
I also get this error.
I am using Ubuntu 16.04.
yad --version
shows0.36.3 (GTK+ 3.18.9)
