Players of Dawn of War Definitive Edition often face a frustrating issue where their mouse cursor drifts to secondary monitors during gameplay. This occurs because the game’s “block mouse to game window” feature fails to function reliably, particularly after using Alt+Tab. The loss of cursor control can disrupt camera movement, especially in critical combat moments.
Root of the Problem
The cursor lock bug stems from an unresolved glitch in the game’s current version. Developers have acknowledged the issue, noting that using Alt+Tab disrupts the cursor confinement mechanism. A patch is officially listed as “in progress” by Relic.
Temporary Fixes to Try
-
Avoid Alt+Tab—use the Windows key instead to switch between applications.
-
Disable extra monitors via Windows key + P and choose “PC screen only.” (Note: This is a temporary measure.)
-
Third-party software like Dual Monitor Tools (DMT) can forcibly restrict cursor movement to one screen.
-
Important: The classic middle mouse button trick from older versions of Dawn of War does not work here.
Official Developer Update
Relic has confirmed awareness of the cursor lock problem and is actively developing a permanent solution. Until then, players must rely on the above methods to maintain uninterrupted gameplay.
