Well I have not changed anything on my PC, and I am sure you have noticed that not long ago I could copy and paste and upload stuff to the forum. There's an example in this thread somewhere that I uploaded. Tis reet strange.
Hosting a file on what?
Hrmm, I don't recall seeing an update to IE 11 for ages, but many other things do update that may also be needed, and MS do have a habit of fiddling with defaults when an update happens. A recent one for W 10 killed a few PCs apparently! BTW. I use W 7.
Oh right, you mean as in Cloud hosting? Hardly seems worth the bother.
