Add "Can't select anything" to FAQ

[Andrew Lentvorski <bsder allcaps org>]

Could I add a question to the FAQ:

Q: I saved my file dutifully, but when I reopened it, everything is 
there but I can't select anything.

A: Check the layers dialog.  The active layer didn't get saved with the 
file.  None of the objects you are trying to select are on the default 
layer.

It took me about an hour of jiggling with things until I hit on the 
solution.  I'd like to save some other poor soul the frustration.

Thanks,
