Good software and I bought it because it enabled me to use a cordless Logitech mouse that does not otherwise have drivers on the Mac.

There are a couple things that annoy me about how buttons work Exposé, however. Maybe a workaround can be offered for these situations if the developer does not soon fix them:

I have my scroll wheel button set to Exposé all windows which it does, however only after I let up on the click. This makes using Exposé require two clicks to use rather than the one I used with a previous mouse: click once and hold while moving the mouse over the desired window and releasing to go to that window.

Also I have another button set to Exposé just my current application's windows, (in Steermouse it's set to replicate a Function key since I can't find another way to control Exposé thru Steermouse) but again, I can't hold down the mouse while I move it over the windows. If I do that, it just goes in and out, in and out of expose mode over and over.
