Need a little help with Startbutton mod

[dping28]

Hello,
had a quick question for you guys, basicly this mod is my first custom ui I have done other than installing others work. what I did was I took the startbutton xml (couldnt get my own new window to work) and I added 2 checkboxes, 2 text boxes, and 2 buttons. Its function is very simple.

Check1 Textbox1 and Button1 were all labeled MA (Main Assist) the next set labeled MT (Main Tank) I type in the names of the people check the box and it locks the box from being editable. I click the button and it issues /target (name in textbox) .

Everything works great except for one small detail. If I have the text box focused the only way I can get it unfocused is to hit enter which then makes my cursor go to a chat box and have to hit enter again. OR I just click the checkbox. Now this isnt a show stopper for me but was wondering if someone could tell me if there is a way to add something to it so I click with my mouse ANYWHERE outside of the tezt boxes they loose focus. Thanks!
