>I have created a custom messagebox class which functions as a drop in replacement for MESSAGEBOX in a touch screen application. The problem is that when I fire my message box, it causes valid, lostfocus, etc. to fire while if I call MESSAGEBOX none of these things happen.

Your code could reset some property (in form or application object) that will block code in all other events (form.activate,control.lostfocus etc).
