I forgot: it also happens with the buttons at the bottom of posts in that view (Edit, Deprecate/Publish, Delete). Only the icon is shown.

Might be a browser thing.
It works ok for me using FF 2

I'm using IE6. A pretty mainstream browser, I'd say. Maybe it's, yes, a browser's flaw, but... it's IE6.

Time to at least upgrade to IE7 or better still FireFox or Opera

IE6 is a dog that MS even recommend users drop.

John: two things.

1. Access from work.

2. Cybercafes.

IE6 is the most common navigator around and should be fully supported. I think.

Can you still manage the Admin using IE6?
If you can't then yes, it needs some IE6 specific attention.

Hmmmm, François told me about this problem a tad ago, but I've never managed to replicate it, which makes it a smidge difficult to debug
