Heres my problem, I have an MDI parent form that has a picture box placed on it. Inside the picture box I placed a textbox and 2 command buttons. The way the app works is that the user types an order into the textbox and then presses one of the command buttons. An MDI child form is then opened up with information on the order. This works fine when there is no other mdi child forms loaded.

However when an mdi child form is loaded, I can longer enter a new order number into the textbox on the parent. I can get focus to the textbox (verified this with debug) but the keypress events for the textbox don't fire.

I've never tried to use an MDI parent form in this way, do I might be missing something obvious. If anyone can shed some light on this I would appreciate it.
