[Steven](http://weblogs.asp.net/stevencohn/) explains a concept I haven't thought about before - the [UI Singleton pattern](http://weblogs.asp.net/stevencohn/archive/2004/04/13/112695.aspx).

Nice concept. Yeah, I can admit that I've done my share of “_Expose this control of the form as a Public Static member_” Sorry. Steven's approach is so much simpler. Definitely something to think about
