Excerpt and question modules

I use excerpt for my teasers, and questions are displayed on the first page as follows:

"question text"
"read answer..." link
"excerpt text"

And I want them to be displayed as:
"excerpt text"
"read answer..." link

Besides this, if the question is too long, it will be displayed in totality, not trimmed.

In my case, I made a CCK field called problemdescription to separate the problem from the question, (see issue http://drupal.org/node/130052 ) and in this way I keep the question text lighter. But I've entered a lot of text in the question field to see what will happen. And the whole text appears on the front page. It should not appear in this way, I guess.

What can I do?
