no upgrade option for one-click install?

I wanted to upgrade Wordpress to 2.3.1, but something is different and I cannot find the screen any more where I could upgrade my one-click installs... I've done this before!

It says "You are also responsible for upgrading your old installations (you can do it from here!) should any critical security holes be discovered!"

Where do I do that? (I've cleared the browser cache and deleted my dreamhost-related cookies, so that's not the issue).

It may have lost the data that it needs to recognise it as a one-click install.

Wordpress is actually easy to upgrade manually anyway so I'd maybe suggest doing that. http://codex.wordpress.org/Upgrading_WordPress

Usually its a case of uploading the new version over your current one and going to an upgrade page.

If you really want one-click though you may want to contact support.
