Ok - first step as always - try it here!
So - this is being written in an external plain text editor and I will copy and paste.
And this is being written in MS Word although it is an older OSX version.
Both copied and pasted in with no problem. This is using Mac/OSX though.
Initial thought is no idea whatsoever. Never come across this one either. Does he have some kind of unusual hot-key mapping software installed?
I figured out I have the very same version here, at a client of mine, tried it and even if I paste plain text, IE8 asks first if I want to allow this application access to the clipboard and upon confirmation the above show pop-up happens 🙁
Can you please try with 8.0.6001.18702 and let me know if you can duplicate the problem please? Is 8.0.6001.18702 still supported/compatible with SP?
Well I don't have any IE as a Mac/OSX user but Steve or Brandon may have this available. We shall see.
I have to say this is one of the more bizarre things I have ever heard about IE and I have not heard of it happening before when IE8 was the latest heap of $%&@. Is this some kind of IE option?
