Mouse Sticking after Mac on for a while

Question

Hi,
My Mac keeps being silly: When my Mac has been on for a while the mouse starts sticking, i.e. when I move it in a steady straight line it will stay stationary for about half a second, then jump to where it "should" be. The keyboard suffers a similar delay when typing. It is not predictable, nor can I reproduce it reliably. It happens after lunch most days, and the only solution is to restart.
It's a Logitech LX3 with no special drivers plugged into an apple aluminium keyboard. It also happens on the trackpad.
So, does anyone have any ideas what could cause it? Does anyone have any tips for enabling logging or viewing the logs. I've looked around in Console and have found nothing relating to the mouse or general HID stack.
Thank you in advance,
Neil

Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
If you can't launch the application, log out or restart the computer and try again.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the Process Name column in the process table to sort the entries by name. Make sure there's a column with the heading User. If there isn't, select
          View ▹ Columns ▹ User
from the menu bar.
Hide the Activity Monitor window (don't close it), go about your tasks as usual, and wait for the problem to come back. When it does, check the process list for two things:
☞ Multiple processes with the same name and the same user
☞ Processes shown in red with the words "Not responding" next to the name
If you see such an entry in the list, double-click it. A small inspection window should open. At the top of that window is a field labeled Parent Process. Make a note of the name of the parent process.
Quit Activity Monitor, and if necessary, log out or restart again. Post the names of the processes that met the above criteria, and the names of their parent processes.
