The Activities, Opportunities, History, etc. tabs at the bottom of the contact Detail View are gone. I'm using Premium 2010 Version 12.0.409.0, Hotfix 3. I have made no modifications to the design (that I'm aware of), it just happened.
Another problem is that the calendar will only show mini calendars at the top. Monthly view is not available.

Follow this Knowledge base article to resolve the mini calendar issue. It may very well solve both of your issues.
If it doesn't move your mouse down to the bottom of the contact detail screen and see if you get the resize cursor, it's more likely it's just been resized than removed.
