I can't import into GHH because the buttons are off the screen. The "Import Block List" "window" cannot be dragged or resized, and the buttons on the bottom of the screen are too far down to be seen or clicked on.
This happens in both a maximized browser window and a non-maximized (movable) browser window.
It also happens in both the 1.6.0 userscripts.org version and the new 1.6.6 version.
This is happening in a VirtualBox VM running Win7.
