Nick Fisher has reported that when he’s running EasyGui on OS X, the launched UI windows don’t have focus. The problem is easy to reproduce.
from easygui import * msgbox("Hello, world!")
He has tracked down the problem. It looks like it is a bug in the OS X version of Tcl.
And he has worked out a solution. It is available at gist.github.com/207825
Nick says, “It’s definitely a hack, but it works!”
