Hi Val, I mentioned defrag as a last resort but feel you should clear out your browser history and cookies as a priority. It's also a lot quicker. To do this, assuming you are using XP, go into the browser and press Alt T for tools. You should find in there a function to clear out your history and many other things too. I believe it is quite safe to clear it all out. As you have not done a defrag before you may find that it could take two or three hours so don't sit there waiting thinking it only takes a minute or two. Reading the StatusBar should tell you how much time has elapsed.

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.
