Unfortunately, I don't think thre's really anything we can do about this; it seems to be just really slow. (The reason it's so slow is that when an HTA file spawns a separate window, it actually launches a separate copy of IE to handle the window process... RPC slows down the whole thing, especially as the window is opening/closing.)

With the latest nightly build of selenium-remote-control-1.0-20080702.030034-476-dist I also encounter problems, when opening a URL (not a window): Selenium waits as long as the timeout is set to and then it replies with an unsuccessful response.
