--- Comment #3 from Hew hewus.owns@gmail.com 2008-07-09 20:50:22 --- This should be 'normal' severity, as it affects map movement with the arrow keys, map rotation and zooming (page up/down etc), and movement in possession mode. Every DK2 player will experience this bug, and it takes significant concentration to avoid.
It's worth noting that pressing any other button (eg. a letter key) will stop the effect. It appears that the last pressed key thinks it's being held down, so if this is an unbound key, it will stop your view from flying all over the map.
This is with native dinput.dll. DK2 is currently unplayable with builtin dinput.dll due to bug 13290.
