A two-button First Mouse refuses to work on a Packard Bell system The pointer doesn’t move, but Windows 95 did not report any Problem detecting the mouse. This is a known problem with some Packard Bell computers and the two-button First Mouse serial version (MN M. It might be possible to workaround the problem by pressing
+ to open the Start menu. Using the arrow keys, highlight
Settings, then Control panel, and press the key. Select the Mouse icon with the arrow keys, and press the key. This will open the Mouse properties dialog box. Tab over to the Quick setup tab. Then, (using the right arrow key) open the Devices tab. Once on the Devices tab, Tab over to the Add mouse button and press the key. The mouse-control software should now detect the two-button serial mouse, and the pointer should now move properly. Unfortunately, you’ll need to perform this procedure each time you restart the system. Otherwise, you should try disabling the builtin serial port and install a different serial card. You might also exchange the serial version fora PS version, if your system has a dedicated PS style mouse port (be sure to uninstall the mouse software if you plan to exchange the mouse. Go to the Windows 95 Control panel and launch the Add/remove
programs icon. Select the mouse product (i.e., “Logitech MouseWare”) and click on the
Add/remove button. When the message Uninstall Completed appears, reboot the system.

If the mouse works along one axis but not the other, it’s usually because of a hardware problem—either the mouse needs to be cleaned or repaired. However, in some cases a software-configuration problem can occur when the mouse driver (i e, Mouse Power v) is installed on a system with Plug-and-Play BIOS running Windows 95, and the mouse is connected to the PS/2-style mouse port.
As soon as you touch the mouse, the pointer darts over the right edge of the screen, and then will move only up and down.
