> - It forgets what you've copied to clipboard. Copy something. Insert another row so that there's space for it. Paste. Nothing happens. Huh? It lost my copy. It does this for a large number of operations and it drives me crazy. I've never seen any other program do this.

Try 'WindowsKey + V'.

It'll bring up a list of your previous copies. Not as easy as 'Ctrl+V', of course, but it does save a bit of time. And yes I agree, Excel's Alzheimer's is quite annoying.
