I have to confess, E-Liam, to the fact that as of this PM I have full file options!!!
I do not understand it! All that has happened since yesterday (when I did not) is an install of the latest MS update (KB870669).
The symptoms were that all menu items ran ok on all but drive 'properties' when accessed from a right-click on the drive in My computer or file explorer, but all other menu items on non-drive (eg .doc's etc) were OK. Mouse is a 3-button PS2 'Media Tech' bought for a few euros in Madrid, I think, but have just been given a Logitech wireless KB and optical mouse for me birfday!
BTW, did you get the files I sent via PM regarding the slow-up?
