Inactive / Active Icons not displaying

[MikeManzo]

Hello -

Trying to do something simple - set active / inactive icons.

When setting an Icon in IB (custom or standard) for either state, it has no effect on the control. The behavior is the same: the control works; the icon does not display. Anyone seeing this?

Thx.
