I haven't had time to work on my Boxster and don't expect to have time until next week. I was able to confirm that the window drops when I use both the inside and outside handle. I used a multimeter to check continuity in the door handle microswitch and it looks like it failed. (I'm not absolutely sure because the probe on my multimeter may be too thick to go far enough into the connector on the microswitch to make contact.)

I think the most likely scenario is that both the door microswitch and the door latch mechanism had faults. My VW door latch mechanism arrived in the mail and when I can set aside two or three hours I will check the system with my durametric. I will then most likely need to disassemble the door again and determine whether to replace or repair the door latch.
