I don't think there is a way to do this. Not unless some how a person was able to get into the software and get rid of the code that makes it a touch screen. Or however that works
This has been discussed muliple times on this website, do a search.
But no there is nothing of the sort, the Opera Mini Browser works this way though. If you don't want a clickable screen get someting other than the Storm.
The clickable screen is what makes the Storm so desirable, you wouldn't want to change it.
