Just to confirm this.  Tech Note 180: MultiFinder Miscellanea

"MultiFinder is a shared environment. Resources that were formerly loaded into
the application heap can now be loaded into the system heap for use by all
applications. Basically, if a resource came from the System file, then it will
be loaded into the system heap, even if the resSysHeap bit isn't set.

Since other applications may need to use system resources, applications should
not call ReleaseResource or DetachResource on system resources, such as
cursors and fonts, nor should they change resource attributes or modify the
resource data directly. Applications should also not make assumptions about
where a resource has been loaded (system heap or application heap)."

Hope this helps
