[ic] mv_no_session causing weird scratch behavior

[Grant]

I'm setting some scratch variables via [seti] that aren't carrying
over to the next page until I add an item to the shopping cart.  Then
it works as expected.  I'm using mv_no_session and when I turn that
off it works as expected from the start of the session.  Does this
make sense to anyone?  My browser has cookies enabled and I'm using IC
5.2.
