Submit Step 3 - Re-edit button

[supudo]

Hi all,

First, nice job guys. Pligg is the first open-source software after phpMyAdmin, i use so intensely. Thanks.

Now back to the problem. When i submit a link, a pass through the steps 1 and 2. On step 3 i decide to go back to modify the description of the link. I click the edit button right beside the submit button. I'm taken back, but the page was expired. Kinda lika when you post a POST form and hit the backspace ot the back button of the browser. It just says the the page has expired. Reloading at that point shows the step 2, but only the title and the url. It doesn't remember the description, nor the keywords.
So is this fixable? I'm searching all day in the forums, and still didn't found any clue to what might the problem. I've also browsed the CVS on the sourceforge and compared the files and whatnot.
Any clue/advice/solution is appreciated!

P.S. Pligg Beta 9.8 (the last version in sourceforge), MySQL 5.0.44, PHP 5.2.4, Apache 2. The server is some *nix box.

Found the problem.
When the php is configured with session auto-start to On, the edit button on step 3 of the submit process causes the form to resubmit itself and thus loosing the information entered. When i set the setting to Off it worked fine.
I'm not sure it's a bug, because it doesn't stop the site from working. But maybe it can be included in the features list.
I'll post a solution if i find one : ).
