visual studio 2008 - Where is the option that lets me edit code which is running in the debugger and then continue with the changes compiled? -

By luck, sometimes I can edit a class, while debugger is running and sometimes not ( On different machines such as on collaborative work)

As the title, where is the option that can edit the code which is running in the debugger and then continuing with compiled changes?

I Visual Studio 2008 Professional Edition SP1

Thanks

Tools / Options / Debugging / Editing and Continue. This is often the case that you will not be able to see the option because another user has not indicated that the 'Do not show this again' checkbox when it first indicates this dialog allows you to reset those options.
