Just out of curiosity...has anyone tried /know what happens when there is only the absolute minimum RAM (taken removable RAM out) and filled (no doubt this would have to be done on purpose and then done a defragmentation and filled again to ensure total disk space usage) the drive...then ran whatever programs would start and tried switching or using large items copied to the clipboard? As VM is never off, what happens? There would be no place to write the info to...does this cause the OS to crash or would it simply refuse to allow the extra RAM action to be carried out... Is this documented somewhere? Cheers, Richard --
