welcome to the forums.
I'm not familiar with XT9, but which 4.0.4 did you upgrade to? Is it the one that came out in January? UVLI4?
Sometimes after updating you may have to do a factory reset to clear up little bugs. You can try going to settings > applications > all. Find the XT9 app, select clear data and cache and see if that helps.
You can also try going to recovery and clearing the cache. If you don't know how
Power off your phone. Hold both volume buttons and the power button at the same time. When the phone vibrates, let go of the power button but keep holding both volume buttons. In a few seconds you should be in the recovery menu. Use volume buttons to move up/down and power button to select. *if power button doesn't work, use your home key*. Go to format cache partition and select it. Reboot and see if that helps.
