What is the difference in the MSAA object handling when using "backwards compatible" mode or not?

Hi, we are currently trying to use MSAA object support in TestComplete; unfortunately the only way we seem to be able to get MSAA-enabled objects to show up as such is to enable the checkbox on the MSAA configuration page that allows "work with MSAA objects in mode compatible with TC 6 or earlier". What we would like to know is: how exactly is this method different from the more recent method, and how can we get the newer method to work with our program? We read the documentation, but unfortunately found only the standard examples of how to enable MSAA, which did not work fo rus unless we also set "backwards compatibility" mode.
