I have been working the last couple weekends to update SysAnalyzer
so that it works with Vista/Win7 and can operate in a 64bit aware manner.
Some of the new APIs make tasks like getting the port/process list much easier. Some of the permission restrictions make other things more annoying.
Everything should be working now, although some features are limited to 32 bit processes only until i code up an x64 helper app to do things like inject dlls, do memory dumps etc.
