You are using !ParseEvars which you don't need to do. And you either can get rid of !Execute. But for future reference every !Bang needs to be enclosed in [ and ].

And what is this..


And actually...now that I look at it...your whole xTrayOnResize is wrong. You keep moving your Taskbar out of the way of your Tray instead of resizing it. And is that even a valid setting? Shouldn't it be something like xTrayOnAdd or something? Damn I wish I had my docs in front of me right about now.
