When I open my macro enabled workbook it has macros disabled...

Is there anyway to get excel 2007 to 'remember' when you tell it to allow
the macros on a workbook, it disables them everytime and I am trying to
automate some processes which is impossible if it wont allow the macros to
run without manual intervention. i am aware of the risks etc but i am a big
boy and capable of deciding if I want a workbook (macro enabled) to be able
to run macros on opening without having to tell it every damn time! Anyone
can help would nost appreciate it.
