What ticks me off most is that the settings for word completion for these stock SIPs still exist in the options screen hence giving the false impression that it must be something I did which caused it not to work. (That's a -1 for you HTC)
After countless futile attempts at configuring whatever options I can find related to word completion, I gave up. Did a google on this problem (should have done this in the first place) and found the cause as well as the not-so-perfect fix for this. Why not-so-perfect? Because its a case of one or the other; you can have word completion in either the HTC SIPs or the stock SIPs, but not both. (That's -2!)
Made your choice? If you are still keen on having word completion for the stock SIPs, follow the steps below:
IMPORTANT: be sure that HKLM\Software\Tegic\eT9\XT9SupportMSSip has a value of 0.
Change these two registry keys under:
- Value of Ime File from \windows\xt9ime.dll to \windows\compime.dll
- Value of Layout Text from XT9 IME to COMP IME
And soft reset. To revert back, simply reverse the steps above.
