[xdebug-general] Re: DBGp - Eval, property_get, & property_value

Just posting the update/resolution...I did get my watch window to work just
how I wanted it to. Once I downloaded the newest snapshot, eval started
working (although I can still get it to crash php.exe if I give it some bad
input), and I was able to get the functionality I wanted.

Thanks!
Jared
