This can happen in ANY app, even on the today screen. It happens if I am tapping on screen a lot, going through menu's or playing games or anything that I'm tapping frequently, then suddenly the screen will completely freeze (though if I'm playing a game, for instance, the game will still be running, sound effects still playing, though the actual frame will be frozen/no animation). It usually stays frozen for about 5 seconds.

Juggalo - as far as it being incompatible, I'm willing to bet that it can be made to work. I've been reading in the Blackstone forums at XDA and seeing that the Touch HD and Touch Pro really seem to have very much in common, hardware wise. There is definitely a high level of compatibility there especially when it comes to video drivers, different things they are trying to get better graphical performance worked on my phone as well (though I saw no real improvement from any of them). The HTC Hotfix apparently replaces a few dll's (I'm particularly interested in the ddi.dll), and their own description of the hotfix is to address the exact issue I described above. To see the exact same behavior on both phones leaves me 99% certain that the fix can also apply the same to both phones... I would be happy to guinea pig the dll files if someone can somehow get them out of the hotfix file. I'm going to try to download it right now and see what happens when I run the .exe on my laptop.

Here is HTC's description of the issue on their support site: "Sometimes the screen stops responding for about 3 to 5 seconds when running an application that needs to use the stylus to click the screen repeatedly within a short time. For example, the windows built-in software like SMS, email, solitaire, etc."
