Hard to express and probably missing the obvious.
User navigates to a page and gets :

Mark the ones you want to cancel and click 'Cancel'

H1 
--- ----
1 Checkbox
3 Checkbox
4 Checkbox
7 Checkbox
8 Checkbox
9 Checkbox
10 Checkbox
....

'CancelButton'

User checks 7,9 and CancelButton submits form and this page comes up :

You're about to cancel following pls confirm

H1
--- 
7 
9 

'ConfirmButton'

Now at this point user navigates to another place by browser buttons, comes back to 'Cancel' page and say unmarks 7, marks 8.
Then he navigates to 'Confirm' page again via BROWSER buttons. Here sees a confirmation is being asked for items 7,9 not 8,9.
Is this a stateless world so strict or is there a way to force it change too.
TIA

BTW I'm currently testing all these with wc shareware and we're gonna buy it in near future. So wc methods are OK (I think I missed one obvious).
