you should check your settings on the Bubbles scr then. Edit: Oops! No speed settings. Does it run normally when the screensaver starts normally, i.e., not with the tool? Then don't start it with the tool - it isn't meant to be a screensaver activation device, but only a tool to access the settings.
And please, folks, when you are referring to a download and/or article at this site, provide links. You certainly aren't the first to fail to provide links, but at least it is fairly clear what you are talking about. In other cases, we have been rendered entirely clueless as to what the post was about. :D

Oh, and ask questions in the Questions forum. Discussions in the Discussions forum. It can make a world of difference as to whether you get an answer or not.
