Guys, Some users often open two different sessions in my application by opening a new browser instance (not "Open in new window" {they all use IE}). This actually works better than expected, the two sessions are almost indepedent. The thing is: almost. Sometimes one session displays data from the other one and things get messed up. Does anyone know how to fix this? Add a hidden PHPSESSID field in every form (instead of cookies) would solve my problem or is this a server-side thing? Thanks!
