InfoPath Dev

I have a Rich Text Box Control on a browser enabled form and it is entering a double line return whenever I hit a carriage return. I have looked through all of the settings and I do not see anything that would cause this. It works fine in the designer mode but as soon as it goes to the browser the issue happens again.

 

It appears that this issue is only happening with the auto expand is enabled on the rich text box control..

Anyone have any ideas?

Bump. Same issue. Have a web-enabled InfoPath form used to collect anywhere from a paragraph to longer than a page's worth of content. The text defaults to double space - how do you make the text single-spaced? Is there a way to give the options or force single space? Thanks!
