I have an old unibody Macbook Pro (non-Retina) running 7.6. The trackpad is one piece and the lower half can be depressed as the button. I typically rest my thumb on the bottom half to click and use my index finger to manipulate the trackpad.
In OS X this works fine and I can move the cursor freely whilst my thumb is resting on the lower half. In OpenBSD I cannot. The cursor freezes if I have two fingers resting on the trackpad - i.e. thumb on the lower half and attempt to move the cursor. I have to lift the thumb off the trackpad to move the cursor with one finger. As you can imagine this got annoying pretty quickly. Is there some obscure X11 setting I can configure to fix this? I've been unable to find anything. Thanks Lloyd
