GUI Design problem: How can I remove space between widgets on a canvas?

[Marc]

Update:

If I use Labels as opposed to Buttons, then they line up perfectly. So
obviously it's a spacing issue with the button, possibly with the raised and
lowered settings before and after it's pressed. I've tried using the
different reliefs, but somehow there always seems to a buffer between them.
I've also tried using the Checkbutton and Radiobutton with (indicatoron=0),
but it's even worse.

I need to have a widget with a command option because I need to peform a
callback when it's pressed. Any ideas?
