Does the latest SP4 merge modules include all previous fixes?

Hi All,

First time on here so hopefully I'm posting to the correct location!!

The reason I am asking this is because we installed SP4 on a development machine and it fixed a bug where margin information set at runtime was being lost. We have since rolled back the SP4 install and downloaded the latest merge modules (labelled SP4) and the fix isnu2019t applied when we once again attempt to build our application.

PC is running VS 2010, Any ideas?
