When spending very long time writing post, I sometime get logged out. When i press submit button, I have to login again then the post submit. At that point of time I see a warning about "invalid thread, pls contact administrator". The good news is that everythings else work, the post is where it should be, etc. I beleive there should not be any warning as everything worked fine. It's only a small cosmetic "bug" (feature ?) but as it say to contact administrator i have posted here. have a nice day.
