do you have disabled settings>general>confirm session saving?

Yes.

Key Settings:
[ ] Confirm "Session" saving (unchecked
Startup: [x] Open Browser
Startup Directory: (x) Last
[ ] Multiple view for same file (unchecked)
[x] Synchronize browser when view is closed
Maximum of view tabs (1)

carrabino - I think you misunderstood what Pierre was saying. I had the same problem as you and it was driving me nuts.
1) Go to Settings->General
2) CHECK (Enable) "Confirm Session Saving"
3) Exit program
4) Xnview prompts to save session
5) CHECK (Enable) "Do not show this message again"
6) Select "No" button

Now it saved the options to not save session and not to prompt you to save session. When you re-open Xnview it should only open with the image you opened from Explorer. You might have to close open tabs first, I don't remember. To change to saving sessions again or to enable save session prompt you have to follow steps 1-4 again.
