Hmmm, probably some of these problems if not all are caused by my having no
documentation at all on how mice work, what codes they return, etc. So when I
wrote the mouse-handling code, I could only test it against my (two-button)
mouse. I had mail from somebody saying that he had to put his three-button
mouse into two-button mode, then it worked. And with other folk it worked OK
without any mods. Experimenting with the baud rate setting seems a good idea;
having it set wrong would certainly give the symptoms mentioned above. I have
no idea how I could put auto-baud rate detection into the mouse handler.
I'll be putting out a new version of selection when the 0.96 kernel appears;
this one supports selection by word and line as well as by character, and
has a more xterm-like selection interface, but the mouse driver hasn't changed.
I'll also be including a simple test program, so you can check for mouse
compatibility without having to patch the kernel first.
I'll repeat my plea for information: If anyone knows of some on-line
documentation about mice at some archive site, please tell me about it.
