When I tried to use kazehakase at luxurymotors.com and mls.ca it failed to respond to various buttons during the search at luxurymotors.com and for a button to accept the terms of the site at mls.ca. I am using the community package 0.5.4 in Arch Linux and their jre package for java. In Gentoo and Debian when you install kazehakase it also pulls in firefox or iceweasel and works at the above sites. I did an install of firefox in Arch linux to see if it would help and it did correct the problem as long as I installed firefox first before kazehakase. You can then uninstall firefox and kazehakase still works so I don't know what installing firefox does for kazehakase but that shouldn't be the way it behaves. At least in arch you can remove firefox if you want a minimal system; you wouldn't want to install firefox just to have kazehakase--kind of defeating the point.

This might be similar to other button bugs submitted but I didn't see any solution to those.
