An anomaly that shows up occasionally in Visual Web Developer

[bernard]

I updated to Prototype 1.6.1, and I now sporadically get a message:

Warning 1 Error updating JScript IntelliSense: C:\inetpub\wwwroot\lib\prototype.js: Object doesn't support this property or method @ 1764:4. If I revert to 1.6, the message goes away. I'd rather not be mucking about with this until i hear some suggestions about what might be causing the message.
