Error handling

Hi all:I came across a problem about error handling.

That is,While the console shows “notes exception:…”,the user’s web page don’t see any error message.

For example,I upload a attachment,and this make the database exceed its mailquato,so the console happens to show this:“Http Web Server:Notes Exception,unable to write to database,database would exceed its disk quato”,but the web shows nothing - -!..This made users confused.

I tried make a $$ReturnGenralError Form,But it don’t come out when this error occur.

so,any guys can help?

thanks in advance.
