Convenient timing hbenz... I was just digging through registry settings right this moment explicitly for T9 settings and was wondering if two particular settings were the culprit...
IMPORTANT: previously be sure that HKLM\Software\Tegic\eT9\XT9SupportMSSip has a value of 0.
This may just be the key and the reason the existing hacks don't work and eventually reverts back. I'll be posting a new cab... meh, right now.
Let's see if this version sticks!
(I'm posting the new cab here, but I'll also replace the two other copies floating around as well just in case people grab those by accident.)
