Concurrent browser close without showing the report

Hi:

I have a concurrent where output is defined as TEXT.  It execute a report and it is suppose to open the browser when concurrent finish succesfully and I use the "View Output" button.

But when I do this, the browser window pop ups and then it closed without showing any data.

Any posible cause and solution please?

I have added two images: "Concu02" is the concurrent definition screen.  "Concu01" is the concurrent execution screen with the message I got when press "View Output" button. Thanks in advance for your responses.

LAST UPDATE:

Hi there:

I solve the problem myself...  It seems that some modifications to the "layout model" in the REPORT is the cause of this issue.  I took an old backup version of the *.rdf files and it work fine.  So I have had to add again all the new codes there.  After that, and WITHOUT change the LAYOUT, the concurrent work fine and the TEXT output at last appears in the browser.
