I installed BufferZone Pro into a W7pro64bit virtual machine and the installer launches the default browser (in this case, IE9) to show you a tutorial. The tut appears to be presented as one large image that did not load:
I was able to surf elsewhere - but their tutorial is broken.
I then tried to install Flash. I left the option checked to let the flash download and install the Chrome browser inside the buffered zone. Flash installed, but the Chrome install failed. I would say that BufferZone Pro has some bugs to be worked out. It is certainly not worth paying for.
