In this case setting osrelease to 2.4.20 will not result in a fully =20 working application. You could pray and set osrelease to 2.6.16. Maybe =20 it works for you. But don't be surprised if it doesn't work for you. =20 We have known problems here. If you started an application with 2.6.16 I recommend to reboot if you =20 want to switch back. I've seen cases where old linux stuff was still =20 in memory even after a program stopped. This results in a panic if you =20 switch the osrelease version (not immediatly, a few seconds after =20 switching). Bye, Alexander. --=20 Everybody is going somewhere!!
