Hello,
tested on lamp and wamp, new install.
I check "choose user group on front" + immediate registering and I create a
new group.
Choose this group on front when registering; user is created but you are not
logged in.
When you register and choose "member" group (default installed group), it
works and you are logged in on "register_complete" page.
Tested with "activation email" option do the same.
This problem disrupt the registration process when you need users to do
something after registering.
Phil.
