Re-linking WP9

I have not been on my computer for a few days, so your question may have already been answered. Also, I'm not sure I understand what you mean. I use WP9, and I often look up things on the net, switch back and forth between WP9 and WP5.1. All I ever do is just click on the little minus and send it to my toolbar at the bottom of the screen. (Being brain dead this afternoon, I can't think what the bar is actually called. I then just go to whatever it is that I want to work in and when I'm ready for WP9 again, I just click and it enlarges and is right back where I started from. Otherwise, I'm not sure what you're talking about "re-linking."
