Goofy Runebook Bug?? Maybe??

[Swunk]

I opened a runebook from my bank box, and then (with the runebook gump still open) I went to GRAB a completely different runebook from my character's hand and it wouldn't *allow me, as if that was the runebook that I had opened. It only let me take the runebook from my hand (which was never opened) after I closed the runebook that I had opened. I hope this makes sense!
