Well, what's wrong on catching all signals? :) It sounds weird, though. > Another problem is that if you run gpm with -R, you break mouse in all > other applications: xserver, svgalib, dosemu.

I'll probably talk with Nico about exposing paralel better designed (not struct-based thus hopefully much better extensible) API soon. A pity that your mail on gpm mailing list didn't get much interest yet, however that list tends to be rather lazy and it frequently takes more than few days to others to reply.. Moving to links-discuss. And, let's crosspost this anyway ;).
