Bug? Landscape, PdfPTable 4 cells, Web App, file damaged.

[Pete Gordon - Users First Lists <lists (at) usersfirst.com>]

I spent all day working on this issue and narrowing it down.  It has  
to do with the use of PdfPTable with four cells in a Web  
Application.  It is unable to be duplicated with a command line  
application.  It generated the PDF file on the command line.

Here is the simple aspx code behind that shows the problem.  If the  
document is not setup in Landscape (rotate) or if it has less than  
four Cells in the PdfPTable or if the Paragraph is less than 15  
characters it generates fine, otherwise the file is damaged.  Whew!   
That was a lot to type...  I found it when I started putting in a  
Paragraph that had a full description (more than 15 characters).

Can someone please verify for me that they are seeing the same  
behavior in ASP.NET with the code below?  And, maybe someone will  
have an idea of how I can address this.  I am trying to create  
absolute positioned tables for label printing (4 labels per page).

I am new to iTextSharp, so please excuse me if this is a simple  
mistake on my part or has been addressed already.

Thanks,
Pete Gordon
