paste to entire column
Please allow us to disable the ability to paste to an entire column. Or better yet, display a pop-up asking if that's what we'd like to do. I've caused Excel to crash numerous times because I have unintentionally "chosen" to paste data to an ENTIRE column(A:A). That would be extremely rare if ever. Excel will lock up as it attempts to paste the data into every single cell in that row to infinity. Depending on what was copied, the program may just crash instead and then I've lost data. Most other errors that users make in which we copy/paste incorrectly is easily and quickly fixed.
I like the pop-up idea. I think I've been waiting an hour or more today for my excel to un-freeze (which it will eventually do, I've waited before) but it is frustrating because i'm unproductive while waiting.
