Since you get a resource handle to a STR# resource (stored in the app 
file), I think you must use ReleaseResource instead of DisposeHandle.
Usr ReplaceResource returns the handle, so you could write:

h = fn Get1Resource( _"STR#", strID )
if h then ReleaseResource( Usr ReplaceResource( h, _"STR#", strID, "", 
prefsRef )
