After much playing around I have solved this issue for anyone who might come across this, indeed the dialog will close if the focus is set to the button in my example I did not include all the code but what this code dose is allow a user to look up a word with data from a database of aprox 30000 words thus the A-z buttons. Anyway the reason the close is you need to have something for the button to do so your identifier cant be $null. When I gave it something to look up Wallah no more close. Thank you too all the helpers here and happy coding.
