Haven't seen the keyboard listed before. I'd guess though that it is related to the clock widget, contacts, gallery etc .... There is a hole somewhere in the framework of sense that is causing all of these random disappearances. The fix is a factory reset, the problem is HTC's and they have been promising a solution since the Gingerbread update first pushed out. Steps to go through before
1) make sure auto back up and restore is checked under settings ---> privacy (looks like a fence)
2) make sure you have your contacts backed-up somehow. There are really 2 options; use back up manager from Verizon, or have them all in Google as contacts.
3) go to settings ---> accounts and sync. Tell it to sync all accounts and wait patiently for the little circle arrows at the top to stop spinning and go away.
4) while you wait go into your app drawer click on the downloaded tab and make a list of those apps just in case the back up and restore doesnt work.
5) do a factory reset of your phone. Two ways to do this too, under privacy in the settings tab or by powering down your phone and then turning it back on while holding down the up volume rocker (it may be the down volume rocker I can never remember) whichever way it is you'll end up on a white scree then use the volume button to go down and select factory reset and push the power button to confirm. Be sure whichever way you go not to reformat your SD card as well. It'll ask if you want to format the sd card tell it no. When it's done go through the setup process just like you did when you got the phone make sire to turn on automatic backup and restore in the setup of the phone. Probably should make sure you connect to wifi right away because the market should start downloading all of your apps shortly after you sign into your Google account.
6) Once you are all set up again and this is the most important step call HTC tell their tech support team what happened what you had to do to fix it .
