I am using Mac OS X with a Kinesis Advantage keyboard and having some issues. I generally use Apple+Tab to switch applications, but when I do this with my Kinesis, it only opens the window switch dialog for a moment before closing; I think that the keyboard is terminating my keystroke early as some sort of accessibility option.
Can I turn this off somehow to allow "long holds" of the thumb keys? I've looked in the manual, but I haven't found anything.
