The functionality of keyboard lock - the key combinations it will actually intercept - is heavily dependent on the browser and platform you're using, and there will always be certain key combinations that will not be passed through. Other folks on the list may have some hints as to how to make it work more reliably, but, in the end, there's not any way to force the client O/S and the browser to let those key combinations be passed through. The only other hint I can offer is to make sure you're securing your site with HTTPS - some functionality, like clipboard and maybe even keyboard lock - relies on the remote site having proper SSL/TLS encryption, and those features don't always activate for plaintext HTTP connections. -Nick
