Sorry about this log but the site is going mad over it.<br><br>Ok, we have just installed NT4 Workstation SP6a at a site running on Acer 4400 machines.<br><br>Shipped with them is the scroll mouse, with the little wheel on top to navigate the internet etc.<br><br>We have been unable to get the wheel to work, and have applied all the patches and updates suggested by both Microsoft and Acer.<br><br>It may be down to a problem where going in to start settings , control panel, mouse / general. We are unable to update the driver as it is greyed out.<br><br>If anyone has encountered this before I would be greatful for a bit of help.<br><br>Thanks in advance.<br><br>Paul <p>Paul Ovey<br><a href=mailtoaul.ovey@avenue-legal.co.uk>paul.ovey@avenue-legal.co.uk</a><br><a href= > </a><br>
