Pdaxrom nethack installs fine, but has problems with the scrollbar sliders (ie they dont work properly, only ever goes down or to the right). Otherwise great!
That's not a bug; that's how the Athena toolkit scrollbars work, unfortunately. The left mouse button scrolls down or right, the right button scrools up or left, and the middle button causes the scrollbar to jump to the cursor position.
Adding these lines to your Netscape.ad file should cause the scrollbar to work better without having to rely on extra mouse buttons:
NetHack*scrollbar.Translations: #override \n\
<Btn1Motion>:MoveThumb() NotifyThumb()
FYI I am working on a X/Qt-specific NetHack X11 package optimized for smaller screens, in case anyone is interested.
