Hi Val you may want to try a programme that I find useful. Its called smart defrag and can be found at www.freedownloads.com go to the search field and type smart defrag it should find it quicker for you. Download it and then run the settup programme. It is jaws user friendly and you can check a box to automaticallly turn your machine off when it is done. It will also run in the background doing its job. Hope this helps. ps there is a defrag facility within windows but this is supposed to do a better job. ----- Original Message ----- From: Val Brown To: jaws-uk@xxxxxxxxxxxxx Sent: Wednesday, March 31, 2010 6:40 PM Subject: [jaws-uk] HELP PLEASE Hi Robin, David and Kevin, thanks for your suggestions, Robin and David. Tried unchecking as Robin suggested and also David's suggestion of the clean manager. No joy with Robin's suggestion but I cleared out an awful lot of temporary files, etc. etc. but, like the genie in the bottle, the "invisible" list(s) popped up again so I reckon its going to have to be the defrag but I don't know how to do it - any step by step instructions please. I always log out and switch off rather than leaving the computer in either stand by or hibernation modes. I even did a re-boot following the unchecking of the tabs and the cleaning but to no avail. I suppose the defrag is the last resort before I throw this machine in the skip! With best wishes Val.
