hello experts whenever i switch to another program window then return to the project i get this error
or if i try to execute the .exe file
An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll
Additional information: Object reference not set to an instance of an object.
the debugger then points to the first line
Public Class Form1
of my project.
i doublechecked that form1 is set as the default form
any ideas on what could cause this?
thanks in advance
