The above comment isn't a bug report, but rather a technical support request. Please use the Red Hat fedora-list for technical support with this problem. You may discover it is not a bug at all. If it turns out that it is indeed a bug, you can file a new bug report against the proper component, which would likely be system-config-mouse, or the kernel. The X server by default is configured to get mouse events from the kernel driver.
