The bane of my existence has been for quite some time the inability to get XDebug to work in a 64-bit Windows environment. I’ve had to resort to running my development AMP stack (Apache, MySQL, NetBeans) in either an Ubuntu x32 or XP 32 bit VM to work around this defect. Of course, I’d much rather not have to start a resource heavy VM to do dev work and this inability to step through a script on my native 64-bit desktop (formerly Vista, now -Halleluja!- Windows 7) always vexed me.
