I just figured it out: you have word wrap enabled in Preferences. When a very long line is displayed wrapped in a Swing text area the Swing UI is unresponsive. It is a known problem in Swing for which we don't have a workaround yet. The bug is that Oxygen should not apply the line wrap preference to the output view of the debugger because the debugger result is most helpful if preserved as is. We will fix that in the next version. As workaround please disable the option line wrap in Preferences -> Editor -> Pages -> Text when you generate very long lines in the debugger.

I get the result document in the Text output view of the debugger on a single line containing 307,318 characters. The the result document starts with <fo:root> and ends with </fo:root>. There is no vertical scroll bar in this view because the whole document is on a single line. I get the same result with Saxon-HE, Saxon-PE and Saxon-EE. Maybe we don't use the same files? Can you check that you tested with the same files that you posted to the mailing list? I attach the files received from you.
