Session Without Cookies

[eluser]Tickk[/eluser]
Hi,
After 2 days using Hybrid Session, I still got the same problem.
But not as much as before. I got 1-3 complains from +/- 300 visitor per day.
Before almost 10 complain every day.

The strange is, some session work for him ( visitor who got problem ), and some session not work.
The session is lost between 2 view from 1 controller.

Any other suggestion to check or modified would be great.
Thank you
