When I plugged it in, it started OK but Outlook just wouldn't run. Repeated attempts, with many hung programs, forced shutdowns and reboots later, I had some error messages about Office Communicator not connecting, so James from the desktop team showed me the way to disable Outlook plugins. You'd never find that on your own! Then it worked fine.
Then after lunch my Macbook Pro stopped working over the wireless network. It was assigning its own IP numbers, in defiance of the setting to use DHCP; that's odd. I'll see if it's OK tomorrow; I deleted all the wireless connections I could find, and turned the Airport off and on several times, and it's quite happily connected to the home network tonight. Computers are like that. How does Joe Sixpack cope, though - even with a Mac, supposedly trouble-free?
