Please, note that some headers in FB 4.4.3 package were not updated.

In the file "Tlbx 8.5 Window Mgr.incl" two missing constants were added:
_kWindowFadeTransitionEffect   = 4
_kWindowGenieTransitionEffect  = 5
Now are still missing...

Even the Util_Files.incl is not the last one.
("usr FSSendFileToTrash" using AE to the Finder)
