Itunes not responding after waking up computer

Yeah this isn't a one-time thing, it happens every single time I wake up my computer. I leave iTunes open while putting it to sleep, and I find it frozen (with the beach ball cursor spinning forever). I'm sick of having to force quit and relaunch since my imac is an old one and closing/opening apps can be painful.

Just for the record, I use ethernet to wifi internet sharing so even if it goes to sleep the hard drives never stops spinning.
