greetings, i have recently built a 4.0ghz system with xp pro (which is the only operating system installed at the moment) , 300gb sata, 1gb ram. i have gone through the settings in "o.s." and each time the computer reboots, i get the usual screen (set to select the default (and only) o.s.) however, i have no mouse control whatsoever! i have selected "default" in/for the "mouse" section under options and still, the problem exist. i should mention that the mouse is a 2-button, scroll wheel standard optical usb mouse.....any ideas?....(yes, as far as i can remember, i did check the cmos to see if if the usb ports are turned on as they must be because the mouse works any other time except when the acronis o.s. program is "engaged")...any ideas?.thanks!
