Here's a tip:
One of the symbol fonts has a character that is
the little circle i icon.
So you can make a normal button with no frame and
use this font and set the label to the right
character (like when making an up/down scroll button).
Then you can use the normal ctlSelectEvent and not have
the downside of your method.
Sorry I don't remember which font/char # it is, though.
