I am having same issue (version .86). It is ok early in the game, but gets worse as game goes on. The farther into the game I am, the worse it is. Had same problem in version .77.
Having the same issue. Today i tabbed out while it hung (damn the garotte) and task manager showed free memory between 0 and 1. (win7 32bit). So i think its a memory issue, which is not relevant on the early bear cubs (where mauling works like a charm) etc. but later in game. Luckily autoresolving without entering combat works.
