.Net application for WT41N0


I have an application running on WT41N0 written with .Net with EMDK 2,7 on VS2008. It is a application with multi features. Its main dialog has 4 buttons. Clicking on one of the button will bring up a sub dialog for a specific function of the application. The sub dialog also has buttons for options that brings third level of dialog to allow user to perform real functions. The issues if the application crashes without exception whenever user exit to the main dialog after performing some operations. Any help will be greatly appreciated.
