These issues are on 3.2.0.7, on a MacBookPro running OS X 10.6.7.
1. I know that there is a known issue in automotive routing, so this may be that, but I just created an automotive route by connecting several waypoints that went on the order of a thousand miles out of the way (for two points on the same road that are about a mile apart). (To be specific, it went from Sequoia National Park to Los Angeles and back to Sequoia National Park.)
Does this sound like the 'known issue'?
2. By accident I hit "Print" on a route, which brought up the print dialog, and then I couldn't do anything other than print - cancel, preview, etc. didn't do anything (and I didn't want to actually print anything). Eventually I quit BaseCamp and that sent it away but that still seems a bit much.
