Hi Colin,
Thanks for the reply - my system (according to System Monitor) has 495.6
MiB memory and the processor is Intel(R) Pentium(R) 4 CPU 1700MHz,
available disk space 29.0 GiB, so presumably should be OK.
When I say unstable, I mean that, with certain applications running, eg
mail and web browser, sometimes everything disappears from the screen
for a few seconds (except the coloured background) and then reappears -
so the system doesn't crash. It's working OK at the moment because I've
only got the mail client open - I just opened Firefox web browser and it
happened again so maybe the problem is with Firefox?
The other problem I've got is with the HP Colour Laserjet 3500 printer
installation - as I said I've installed hplip-3.11.7 and everything
seems fine except that, when I print the test page from the HPLIP Status
Service icon all features appear correct except the Color Wheel - the
colours don't look right according to the lettering around the wheel.
No - I'm not using the Unity interface because I got the message that my
hardware isn't adequate for that - so I'm using the Classic interface.
