StrokeIt is fantastic here, on Win7 x64. But I've run across one small problem. The \Down gesture does not work. I've set a small media wave to play as a test, and both Up and Down gestures work fine, but not the diagonal down gesture.
Ah, Leo, you're a genius! It hadn't occurred to me that there might be a conflict. Both Mozilla Firefox and Thunderbird identified as MozillaUIBrowser, or something, and Firefox was set to open a new tab with the \Down action. I deleted that and T-bird began acting properly.
