I don't know if it's just me, but I notice that switching web pages seems slower with WindowZones installed. Is this due to it checking if it is safe or not?

No, actually WindowZones adds no overhead. It doesn't do any live checks when you browse to a new site, for example.
WindowZones works by locking down the security rights of Internet Explorer, which shouldn't have any impact on speed.
If, however, there were some other bug in WZ that was causing slowness, you'd see the CPU peg for a moment using taskmanager.
If you do see that, or if anyone else detects a slowdown, please let us know!
