Dear users,

I have written a sample program that ran correctly with earlier than
Mac OS 10.6. The answer field Label does not align correctly. I
downloaded the latest Python 2.7 release but still did not solve the
problem. Look for line "L4.place(relx=0.32,rely=0.56, anchor=W)"

DO YOURSELF A HUGE FAVOR AJ... Learn how to use the "pack" and "grid"
geometry managers available in Tkinter before it's too late. Well,
unless of course your a sadist. In that case just ignore my post
completely. 8^O

I know the pack and grid. They do not allow me to position my widget
the way I want.
You have to go back to first grade and relearn the phrase “If you have
nothing nice to say do not say anything at all”.

The underlying Tcl/Tk is more likely to be the cause of your problem, so
you'd have to look at that.

I'm on Linux with Python2.6 and Tcl/Tk 8.5, and don't see a misalignment.

Stab in the dark: try creating L4 with explicit padding:

L4 = Label(..., padx=0)

PS: Rantingrick is right; you should use one of the other geometry managers

Incidentally I was actually writing a version of the OP's script using
the grid manager when i found his nasty response. So I think i'll just
keep it for me self now. Good luck AJ. ;-)
