Help again with ILS Landing POST SP1

Hello Fellow Simmers,
Thought I had this all worked out and committed to memory.
Flying ILS - Set Nav Radio to ILS Frequency - Set CRS to setting shown in Route -
When I get ATC to turn such & such heading for localizer, I then turn on approach mode - leave alt & heading activated in AP - turn off auto throttle and adjust my own speeds -
The approach captures glide slope, and I descend, keeping speed in ratio to glide slope diamond on HSI - Get a mile or so from runway, and it just wants to take me into the ground - (immediately turn off AP and in most cases I am able to do a safe landing) -
In the past, prior to SP1, this and many other approaches have worked flawlessly using this method - (AFTER I read the many posts here and "how to do it right" - )
Am I missing something here or just "could" it be an SP1 issue?
Your help is "always" appreciated.
