cant delete in forward message

[bbarrons]

I just ran into something that I have not seen yet in the forums or at least I didnt find it in my search. This is the third time in 3 days that this happened. I go to forward a message and want to either delete a portion of the forward or get rid of some of the email addresses and cant delete anything. I can input into the message and delete what I input but none of the forward message can be deleted including my signature at the bottom. I cant delete with the delete key, or backspace, or even select and right click. it just doesnt work. Anyone else seen this and if so, how did you correct it.
