Using with jqueryautosize

I am trying to use your highlightTextarea with another jqueryplugin called "jqueryautosize" which dynamically autosizes the height based on the content in the textarea.

I know highlightTextarea is a bit picky about specifying height and I'm having some issues with incorrect highlighting positions when using both plugins together. I think it has to do with the scrollbar either appearing or not based on what is in the textbox. Do you have any suggestions on how I might get around this issue?

Thanks again for a great plugin. It really helps me.
