response.unbuffer

Hi there,

I have a problem with the use of response.unbuffer and flush If wrote a 
small .spy Page that starts a calculation on the server that last few 
seconds. To show some data while the calculation is running I tried to 
use respose.unbuffer().
The data is shown while the page is not loaded completly but when the 
spy page is procesed completlty i get the following exception. If I 
dont use the response.unbuffer() there is no exception.
Any Ideas?

Tnx!

Matthias
