Wanted to purge any Windows desktops of old versions of IMT now that the Mariage project has been migrated to 1.8, so I booted up the two remaining ones, removed 1.7 and installed 1.8. I did updates on the Vista PC, and on the XP machine I discovered that SP3 had not been installed, so I let that do its thing; then there was another round of updates after that. I also booted up the Ubuntu desktop and let it update itself -- for some reason it can only do that from the command line. I figured I might as well do the rest of the public workstations, so I booted the two Macs and did all the updates on those too, including an excruciatingly slow Adobe update on the dual-monitor Mac. All five of those workstations are now updated.
