Hello,
I am using xboard under Arch Linux with a 2-button mouse.
I cannot setup board with 'edit position'. Mouse right click will give only a black pawn on a square; 'shift' + right clik will give a white pawn.
The manual says the 2nd or 3rd mouse click will bring up a menu; but I tried all combinations of my 2-button mouse and no menu appears. So I can now only set board positions with only pawns!
