I use lyx for word-processing:
together with glipper and the option: "middle mouse button" i get weard behaviour, i cant mark words with the mouse in lyx, so it breaks copy and paste, which is essential for word processing.
if i mark things/words with the keyboard everything works fine.
I also filed this bug in
at the lyx guys. They think its your fault. I really dont know, i just want to keep using middlemouse-insertion with glipper, i totaly love that with linux (anytime im on windows or even mac ;) it drives me crazy that theres no middlemouseinsertion...)
