I guess I'll be able to fix the problem by
implementing an invalid state template which will
present users with a choice when this happens, to go
back and re-submit if they wish.
Before I wasn't setting any invalid state screen or
template which made the whole process transparent to
users, which I much preferred.
So if anyone has any ideas as to how I could address
this issue while still disguising it from the users
I'd appreciate any feedback. Perhaps there is some way
to detect a new browser opening and prevent the
SessionAccessCounter from incrementing?
thanks,
Lou
