That's not very funny when all you try to do is watch a Live Meeting on another Vista feature on your Vista box (last time, I was saved this problem by LM on Vista not being able to connect to the audio stream). And I thought the last time I saw a system swap itself to death was on Windows 3.0...

In other Vista news - try this: right-click on a .zip archive of your choice, select the Open With... option from the context menu. In the dialog that pops up expand Other and choose Internet Explorer. Fun ensues.
