Hi Simon,

It is probably OK (Cayenne Milestones/Betas tends to be relatively stable,
but there is a greater chance for issues).  I was more concerned with a
3.1->4.0M3 issue being present, but since you started out with 4.0M3, best
to stick with it.  We'll help you figure out the problem you are having, or
if a Cayenne issue, fix it.

Thanks,

mrg
