I've created a custom solution on a development server with DW version 19.1.0.5.
I can login as admin/Administrator just fine in firefox, but not in internet explorer. The server has a proper URL, so it's not accessed via localhost.
It seems to accept my username & password in explorer, because i see the bottom graphics for admin interface, but then it redirects to the login page. Checking the "Remember" checkboxes does nothing (works in FF though).
It seems like cookies are not being set properly. Any help would be greatly appreciated.
