I tested with Python 2.1 on Mandrake Linux 8.0 and it works fine. My tcl/tk version is 8.3.4

Do you know the tcl/tk version you have? If you don't, you can get it via:

 from Tkinter import Tk()
root = Tk()
root.tk.eval('puts $tk_patchLevel')

I suspect a bug at tcl level. So can you execute the following tcl script:

-------
entry .en1
grid .en1 -row 0 -column 1

label .lb1 -text "CAN WRITE ->"
grid .lb1 -row 0 -column 0


label .lb2 -text "CAN'T WRITE ->"
grid .lb2 -row 1 -column 0

entry .en2
grid .en2 -row 1 -column 1
-------

It is exactly the same as yours in tcl syntax. To execute it, just save it to the file script.tcl and type in a shell:
wish script.tcl

(The "wish" command may include a version number, such as "wish8.4")

If the script above shows the same behaviour as your Python script, then it's not Tkinter's fault, but tk's. You should then report the bug to comp.lang.tcl.
