SPARQL results text field performance

[kal]

Ran a CONSTRUCT query that returns about 550kb of RDF/XML as the results. Although the text displays fine and scrolling is not a problem, any attempt to select all or part of the text or to copy the text to the clipboard results in a long (multiple minutes) period of the app being unresponsive. This does not seem to be a memory issue, nor is the Polaris executable CPU bound according to task manager.

It may just be that a different text display component is needed.
