[Tkinter-discuss] Need help on gui focus l

[Cam Farnell]

The behavior of your tcl script is identical to the Python code so it's not Python causing the problem. I'm running Ubuntu 8.04 (Hardy), Python 2.5.2 and I don't know enough about tcl to find out its version. The file /usr/share/doc/tk8.4/README says it is 8.4.16.
