Well, there is one thing which could be confusing the poor old bugger:
The post/preview buttons, and others are switched around - and it's not quite so easy to move to the next page - there's no next button, you have to press the tiny little number for the next page.
If you're sight impaired (or should that be site impaired?), then I can imagine that this adds a certain degree of confusion - and, if you're verging on Alzheimers too, well, you're probably beyond help or any changes that could be made here!
