Yes. Long-press the input field. Select "input method" and then "touch input". Wait for the stock HTC Sense keyboard to come up (a second or 2). Then long-press again, select "input method" and then "swype". This will likely fix the problem.
Since Swype is still in beta, it's not perfect, and this happens every once in a while. Every single time this has happened to me, this fixed the problem.
