Gerry,
I have not heard of this being a problem. And I have just a few days
ago used an Option Group with toggle buttons, in an Access 2007
application, and it worked fine for me.
Here's a test... in design view of the form, see if you can drag any of
the toggle buttons *out of* the option group. If the toggle button is
truly a part of the option group, the border of the option group will
grow so as to keep the toggle button "inside the fence" when you move it.

Thanks, Steve, but I had checked that already.
I think I finally found out what is wrong. I had opened the form from VBA:
DoCmd.OpenForm "...",,,acReadOnly
Once I deleted acReadOnly, the buttons worked fine. I still do not see the
logic behind it, but the proof is in the pudding, isn't it
