I have been using the improved CustomUI editor that Paul mentioned for a while now, and it is a really bug improvement. I am not going back.

One thing it has is the ability to open multiple files, which is nice, but:

- I find that I can open the same file twice, which is odd, byt also can be confusing if you open it, save it, make some changes it Excel, re-open to use the latest version. Does everyone else see this behaviour.

- the 'Close Current Document' option doesn't work for me. It closes all documents and the app. Again, what do others see?
