I can confirm this with normal hardware (PC, UNIX, WIN, NS, IE).
I noticed a weird behavior in the "sub create_cookies" of Server.pm.
There is a "if construction" like

if (defined $expire or $Vend::Expire) {

and it seems to me, MV goes into the body of this "if construction"
always. At the first access of any catalogs, $expire and $Vend::Expire
are always empty (undef?). I have set

SaveExpire    8 weeks
SessionExpire 10 days

and I don´t get a right cookies. If I insert some lines like
(ATTENTION: This is not a patch!!!)

	my($time) = (@_);
	$time = $time || time();
	$expire = $Vend::Cfg->{SaveExpire}; 
	$Vend::Session->{'expire'} = $Vend::Expire = $time + $expire;

I get the right cookies now! Another "strange" (?) behavior is ...

- catalog has a frameset served by MV
- one frame has a navigation bar with right URL (with id=xyz123UW)
- visiting the catalog with any browser without cookie
- order one item
- I get the basket with this item displayed
- click the links "Cart" at the navigation URL
- No item in the basket

or

- order one item
- I get the basket with this item displayed
- order another item
- I get the basket with the another item displayed only
  (the previous item is away)

With MV3.14-3, I don´t lost any items with the same machine, OS and
browser.

Any hints, helps and suggestions are very welcome!

Regards,

	Joachim
