Hi,
Very odd issue I'm having. I've uploaded a new website and have WordPress 3 running. Everything was fine for me on my PC however my client is on a mac and couldn't see how to upload images (the browse button missing).
So I tried on my mac also, not browse button. I have tried changing the theme to the default theme and the same issue - so it's can't be theme.
I've tried it with WordPress 2.9 and no problems.
Seems it doesn't matter what browser I use, it just doesn't work on a mac. Strange? Any suggestions?
