Word Press upgrade glitches

My handy hints for upgrading to WordPress 2.0.1 are:

1. Read the instructions

2. Really read the instructions

3. If you realise halfway through the upgrade you’ve forgotten to read the instructions then at least remember to finish the upgrade. Don’t, as an example, upload the new admin files but forget to upload the new include directory as you’ll waste half an hour trying to work out what has gone horribly wrong.

I’ve more or less sorted out my woes, but for some reason I can’t write new posts using Firefox. I’m using Opera instead, the reason I tend to use Firefox more is that it copes with the Discworld MUD better.
