fyi .. in my particular case I have since found the issue is to do with issues with support for the PS2 keyboard port in >= 10.04 and Microsoft Wireless keyboards (see thread http://ubuntuforums.org/showthread.php?t=1546149&page=2) .. by using a PS2 to USB adapter, the issue has been worked around
I figured I should post that workaround here in case a subset of the folks that are having problems may have a similar setup.
I will check if there is already a defect relating to the PS2 keyboard port.
