I can't remember if this was a bug in the original game or if it's specific to this version, but I'm noticing that sometimes when I right-click to look at things, sometimes it doesn't automatically go back to normal and remains in look mode until I next right-click. Like for a while I can right-click on a thing to read a sign and after reading it, I can start moving right away; but after a time it will stay in Look mode and trying to move just moves the view window.

Possibly related is that once that happens, when trying to select a new spell to cast, rather than selecting the spell, clicking on it will instead bring up the window that lets you read about the spell (what you'd normally get when holding ALT and clicking on it). Pressing the keyboard key related to the spell does select it, however.
