Hi Jurgen,
Just realised you had provided a good trace of your problem - apologies!
I think I was wishing that I had a good trace of the similar issue I had
with the tooltip manager!
You might still look at your sarissa version and whether that has any
effect on Explorer if this is updated to 0.9.9.4 and I was wondering what
the exact version of firefox 3 is that you're using eg. 3.0.7.
As I mentioned, I have seen a similar problem before under early FF3 but
with the tooltip manager. I also recall seeing this problem when the xml
request parameters sent to the server were invalid, so it might be useful
to look at the server logs if you haven't already eg. was there was a
parser error from Jeeves when it tried to read the request it was sent?
Cheers and apologies for the misunderstanding,
Simon
