Issue #112 open

Graphic Tablet Jumping Cursor

Anonymous created an issue

Hi, I'm currently running the latest version of Boxer for Mac (1.1.1) and am having an issue using my graphics tablet. I have a Wacom Intuous 3 using it in "Pen Mode" Unfortunately whenever I try to play a game using Boxer, if I try to click somewhere the cursor jumps to be somewhere else. The cursor follows the pen perfectly fine, but as soon as I click the cursor moves somewhere else. Sometimes it's close, sometimes its far from where I was originally pointing.

I'm not sure what has caused this change because I upgraded to Lion (OSX 10.7.1) and upgraded to the latest version of Boxer at the same time. However I am aware of some issues with Wacom Products and OSX Lion, but I wanted to let you guys know in case there was an issue.

I CAN play with my Magic Mouse, however I prefer playing certain games with my Pen.

If there's any further information I can give please let me know. :)

    OK, I'm able to replicate this on 10.7 with my own Wacom Intuos2 tablet. It does not occur in "Seamless mouse pointer" mode, only when the mouse is locked to the DOS window.

    When the mouse is locked, Boxer uses a different mouse-tracking technique - all cursor movement is handled relative to the previous DOS cursor position, instead of fixing the DOS cursor to the OS X cursor's absolute position.

    OS X 10.6 does not exhibit this behaviour, so I believe this is some change to the relative mouse event functions in Lion. Seamless mouse pointer mode is not compatible with all games, but it's a suitable workaround for now for the games that do support it.

    (I should note that 10.6 has different problems with tablet input: the cursor is able to leave the confines of the window even when locked, though this is not obvious because Boxer hides the mouse cursor. This allows you to accidentally switch focus to other windows and generally makes the mouse-locking too unreliable to be useful on a tablet. Interestingly, this problem is now fixed in Lion!)
