When I open mine, it's either library (after reboot) or the place where I left it to (relaunch), so... Have you tried leaving it to library and relaunching it?

itunes is generally run because I plug my phone in, rather than because i ask it to. My own experience seems to jive with what you say, though. Plugging in the phone has it load the store without regard to what panel I had itunes open to before.
