John--
Thanks for looking into this. Here's what's been happening, AFAICT:
I insert a CD to rip, and if my EV-DO connection is dormant, MC will almost always fail to wake it up. If I (successfully) send for a google page through firefox, my default browser, while doing this, MC will connect more often than not. NOTE: other web sites or programs have similar issues connecting through the EV-DO, more or less. MC is one of the less successful.
The few times I tried it, once MC failed to connect, the right-click method NEVER succeeded. I just tried it as an initial attempt, and it didn't work, either. Track record for the right-click method: 0-10.
