You do know the values are changed at the bottom of the page and not on the highlighted item itself, right? There is a 'value' box. Don't want to sound insulting but I don't know how much you use it.
If you don't get the I in the 'value' box try a right click and select all, then type in what you want and it will replace what is there.
As for why the 'I' is not showing I don't know. Maybe a re-intall? Or have you tried the delete and backspace to see if maybe the 'I' is the same color as the background, but it actually there?
Just some ideas, until you get an answer for someone that actually knows what he is talking about.:rotfl:
