Comment 16 for bug 162790

I'm running Lucid Lynx. I have a PS/2 mouse hooked up to a "PS/2 to USB" converter (my keyboard is hooked up to the same converter) to my PC's USB. Here's a simple way to verify the bug without running Firefox or any other application:

Open "Mouse Preferences". Position the cursor over the little light bulb that tests double clicks. Scroll the mouse wheel up exactly once. It is not necessary to click the wheel or to scroll wildly or to move the mouse. Just scroll the wheel up once. The light bulb lights up as if you double clicked. This shows that the mouse is sending signals that are not interpreted simply as "scroll up". I don't know exactly how the signals are interpreted, but I don't like the way that various applications (including Firefox and Chromium) interpret it.

modprobe did not solve the problem for me. I've seen suggestions that the problem can be solved in xorg.conf, but of course, Lucid Lynx's X server does not have an xorg.conf.
