I've actually had the opposite happen to me. The keyboard just drops when I'm texting. I've rest my phone and it seems to be fixed. It's almost as if the screen was registering another touch on the messaging hub making it the keyboard drop. I don't really know, but it was annoying.

Definitely seen the minimizing of the keyboard board while typing. Think its also it registering a tap outside the typing area. Even worse for me though is every now and then it won't capitalize the first letter when I start typing. Sometimes I have to double tap for it to capitalize or click out of the box and back in.
It happened to me for the first time tonight. I was trying to sign into a web site in IE, and midway through typing my email address it simply disappeared, and nothing I tried would bring it back. I had to back out of the page and go back in before it would work again.
It happens very often to me. The keyboard hide away, but its not like a input outside the typing area, cause if you notice, the "cursor" stays blinking where the input should be. A tip that works for me: touch anywhere on the screen and touch the typing field again.
Very annoying. HTC Trophy here. This started since oficial Mango, with the drivers. Which is ironic.
