What’s new in Boxer 1.2.1:

Rendering fixes:

Eliminated screen-tearing in fullscreen and windowed mode, woohoo!
Fixed crappy fullscreen performance on certain Mac models.

Game compatibility fixes:

Fixed crashes and broken CD imports when importing GOG.com games that contain BIN+CUE images (affected Dungeon Keeper, Castles II, Redneck Rampage and others.)
Fixed CD copy protection in the GOG.com release of Pro Pinball: Timeshock.
Fixed hang when switching CDs in Broken Sword: Shadow of the Templars.
Fixed crash when launching Comanche 3 installer.
Fixed hang when launching FIFA ’94 installer.
Fixed CD copy protection in abandonware rips of Steel Panthers 2.
Fixed juddering animations in Commander Keens 4–6.

Input fixes:

Updated Joypad integration to improve joystick mode switching.
Fixed keyboard lag in other applications when Boxer was busy and “Ignore OS X hotkeys while a game is running” was enabled.
Fixed (thankfully rare) issue where keyboard stopped responding after quitting Boxer, when “Ignore OS X hotkeys while a game is running” was enabled.
Improved mouse pointer behaviour when “Use seamless mouse pointer” is enabled.
Fixed keys sometimes getting ‘stuck’ if Cmd was pressed while they were held down.
Fixed controller axis mappings for Thrustmaster T.Flight HOTAS stick.

Other fixes and tweaks:

Removed choice of DOS Games folder location when launching Boxer for the first time. This now defaults to Documents/DOS Games, though the location can still be changed later from the Preferences window (or moved/renamed in Finder.)
Fixed bug in Inspector panel that was preventing changes to settings from getting saved occasionally.
Fixed notification icons and bootleg cover art being scaled incorrectly on OS X 10.5.
Boxer now always auto-pauses in the background while waiting at the DOS prompt.
Made help pages look tidier and prettier.
