When you use track all monsters in track range 'see' you the same way you see them. They will use defensive skills and offensive skills with higher range than their max vision range fe. alchemist will start to throw bombs at range 15+, wyrms will breath even when you are 15+ squares away etc
On higher difficulty levels using track can mean almost instant death because you never know what's there outside your vision range. It can be rare with some high range spell or normal mobs with long range skills (like drakes)
//edit
To be precise Im talking about situation where obstacles wouldnt normally block you vision (open spaces, long corridors). Mobs dont do illegal attacks (no shooting through walls etc) but they seem to have extended vision / share vision with other mobs and attack you "offscreen" from super long range

Re: Track vision bug
+1 it is indeed an strange bug, because some monsters seem affected while others don't. This bug can lead to abuse; I once, for science, killed a whole room of enemies just using track because one enemy kept using one aoe skill each time I tracked him.
