Remember when hordes of WinZip enthusiasts flooded messageboards with angry complaints after XP was released with that functionality built in? Neither do I.
Have you used the most recent WinZip? I had to install the demo to open a .zipx file that nothing I had would unzip. It's a little scary - they've gone quite markedly beyond what you would expect from a compression tool.
It's the developers who flood with angry complaints. And yes, they did. It's called Netscape.
