this main window, have other form use setup

using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.linq; using system.text; using system.threading.tasks; using system.windows.forms;  namespace circbot {     public partial class mwin : form     {         public mwin()         {             initializecomponent();         }          private void newbottoolstripmenuitem_click(object sender, eventargs e)         {             bsetup bsetup = new bsetup();             bsetup.show();          }          private void quittoolstripmenuitem1_click(object sender, eventargs e)         {             application.exit();         }     } }

this setup window

i suspect causes problem fact you're doing this.close() , gets disposed. after calling close() go for() , try operate on possibly disposed resources.
