I haven't tried OS/2 yet, but the documentation clearly claims that virtual memory is done in 64k chunks. I doubt that IBM would have let it out the door if there was a problem such as you describe, and I see nothing in the current buglist which would indicate problems restarting any pagefault. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
