Odd.  I am testing with the following code:
#include <vector>
static void testTypedefTypeList()
{
	typedef std::vector<int> int_list;
	typedef std::vector<int>::iterator int_list_iterator;
	int_list my_list;
	my_list;
}
can you try adding this code to a cpp file and see what results you get?
Do you have:
VA Options -> Advanced -> listboxes -> Get content from default Intellisense
turned on or off?  I have it turned off when doing these tests.
