Bound RichTextBox

Simplest case. I have a RichTextBox bound to data through Adodc. A CommandButton toggles SelBold on/off and returns focus to the box. This works fine unbound. Bound, it works once, ie, the text remains selected and SelBold is toggled. If the button is pressed again, a bunch of Adodc events fire, as well as Box_SelChange, setting the cursor to the start of the text with no text selected. Then Command_Click fires, but of course it's worthless. As they say in the commercials, what's up? Thanks for any input.
