Afternoon all, I have tried to search through the archives but I ca'r find anything to help. The problem is that my problem does not cause a specific error. As of yesterday firefox and a few oter applications do not work. Most times when I start firefox the browser briefly opens and then closes straight away. On some occasions it stays open but after a minute or to of browsing it hangs. When it does this there is no way to close the browser other than to reboot the Acer. Sorry if this is a bit vague but that is all I can offer at the moment. Is there any logs I can check to see when is happening. I am new to Linux so can't do the simplest of things. The only change I have made recently was to set up enrcyption on my wireless network. I did this a week ago with no obviously problems. Could this have caused a problem? Cheers for any help.
