I've been having the problem with the Shift key as well

Versions h and i do it but not g or f
certainly not related to the area I'm in as rotating the camera works fine as long as I don't hold shift problem gets worse as I add more clients
1 No problem at all, 2 not noticable 3 starts skipping and 4/5 are unsuable

update as soon as I use overide(keyclone not passing keystrokes) problem goes away and I can hold shift and rotate the camera again

I have uploaded my keyclone.ini and I'll see if fraps can record it
