Thanks for anyone's help, but I downloaded and I'm trying out VS 2.10 for VS 2010, downloaded the correct
version of XDebug, and made sure the I'm using the following project properties in Visual Studio:

Debug Mode: Builtin
Debugging Type: php/javascript debugging
Debug engine: XDebug

The rest I just used defaults. So my question is why can I not debug
javascript (i.e. it is not hitting my breakpoints)?!? Is it because I'm using the trial version?
