Pane Hangs if page is too large.

What steps will reproduce the problem?
1. Create a new Instance of JSyntaxPane for XHTML.
2. Add all the text found in the web page http://www.PsiqueWare.com/main
3. The UI will hang

What is the expected output? What do you see instead?
I mean I was expecting to see my text in the pane, that's fine if it takes
a while to process the colors, but the pane is expected to be usefull in
the meantime. I can resize my window but the pane component is just hanged
and wont resize.

Please provide any additional information below.
In another application I had a similar problem when loading huge chunks of
html. Mostly becuase html parsing is difficult and slow. What I did is to
use a different thread for the parsing that way it would halt the whole
page, does that makes sense? I hope I can help somehow.
