A couple of weeks ago I updated my LXDE installation, and since then I have had problems, especially with printing. The update was faulty, I was not aware of any problems at the time - but I generally don't check all the output - I'm a default kind of guy!
When I later went into synaptic to try to resolve a printer problem I got a lot of warnings about more than one version of programs being installed, various gutenprint, samba, and openbox files. I found that newer versions had been installed without removing the older ones. I've gone though the list and removed all the older versions - but I still have a problem with the printer:
When I go into the PCLOS control centre to re-install the printer I cannot get the printer configuration windows, clicking on "set up the printer ...." just puts me back into the hardware screen - other applications form here do work. (The printer does actually work, but I want to change the defaults and I only know how to do this by removing and re-installing the printer. - Epson NX200 3 in 1.)
