I've just got my new computer and upgraded to FS2004.
On FS2002 I had a glitch with my sidewinder 2 (from new) which caused me to select options/controls/calibrate joystick/properties/forces/ok/ok every time I entered to make it operate.  Now with FS2004, that doesn't work.  It switches on at the forces screen and turns off again when I exit.  Can someone help me?  After 4 hours I'm sick of holding the stick on center.  I get the impression that other people think that wierd vibrating at take off is normal... it's not!  I'm annoyed that M$ would put a product like this on the market and not offer a fix.
