the only solution i found is clearing all cookies, making changes, and pressing just one time on "preview" then submit. this doesn't feel right.
so where can i report this kind of bugs to slashdot?"
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Always try to do things in chronological order; it's less confusing that way.
