Multi-Site with Domain Mapping Anomalies

Hi - just set up a new multi-site (have set up 3 before) and have a couple of challenges:

* Multi-site not showing on drop-down list for same from black admin. menu under "My Sites" -- show in network admin., but not on menu

* On public site, secondary drop down menus are blank, but not in admin area (ie. for items to show on hover over "Network Admin.)

Can send screenshots.

Thanks - Scott
