IndentFirst Problem

[Diego A. Puertas F.]

Hello list, at last, my thesis is finished, but I still have a problem
with the IndentFirst package.

IndentFirst is indenting allrigth all the first paragraphs, except for  
the ones that are after a enumerate, description or itemize paragraph.

Anyone, can help? I'll apreciate very much your anwser on this one.

Thanks.
