There are only two hacks I can think of which might help:-
1. If you are using the HTTPRequest object to download the XML file,
this can be set to synchronous or asynchronous (i.e. the function that
called the HTTPRequest can still keep running) download.
2. You could spawn a pop-up window/modeless dialogue box or
IFRAME(?) to do the download, as these are in some implementations
effectively a separate thread.
For instance, I use a pop-up window to provide a progress bar for a
function in the parent window. The parent window function can send an
update to the pop-up window without interrupting the parent window
function.
