Derek,
I forgot to mention that if you are unable to identify the programme causing the problem, there is a work-around that will give you a warning when the cookie is about to be deleted.
Open Windows explorer and go to C:\window\cookies (substitute the drive letter where windows is located if not on C: )
The cookie for another forum will be called something like "
derek bolton@www.another forum.co(2).text(You may have more than one, the number in brackets being different. to keep things simple, we'll protect them all.)
Right-click on the file(s) and from the pop-up menu that appears, left-click on "Properties"
At the bottom of the next window that appears, you will see attributes - put a tick in "read only" - do this for all the files that bear this name.
The files are not protected from deletion, but if the deleting programme is well written, whenever an attempt to delete is made a window should appear saying that an attempt is being made to delete a rea-only file "XXYZ" and you simply answer NO.
John.
