Overlapping fragments when using with tabs?

view story

http://stackoverflow.com – First off, thank you all for this great community. I am attempting to following the support demos sample code for implementing a tabbed-fragment interface. Top level, I am trying to implement two tabs, associate a single fragment with each tab and have the fragments appear when each tab is selected accordingly. Currently, I have two issues (but I am sure they're related...) 1) The fragments for each tab are overlapping each other. This could be related to improper fragment attach/detach. 2) A third mystery fragment is being created somewhere and overlapping the other fragments as well (HowTos)
