_ Solved! firefox + kinput2 = pull-down menu don't work !?

When I use kinput2 for japanese input method with firefox, pull-down menu of firefox don't work!

I have to apply a patch for libX11 and re-build it to solve a problem(see Fix bogus timestamp generated by XIM).

you can get a source of libX11 from Slackware site.

$ tar xvvf libX11-1.5.0.tar.xz
$ cd libX11-1.5.0/

and you can get a patch for libX11 from here
