I understand, and I'm sorry if I sounded flip - I didn't know you if you would find it difficult or not. While installing and updating scripts yourself can be quicker and more versatile than using "one-click", many people find it difficult, so you are not alone
Many who initially use the "one-click" install don't realize they can "update" it themselves without using the one-click installer/updater, hence my suggestion to check out wordpress.org for "manual" update instructions.
If you want to update via the "one-click" installer/updater, you will need to wait until Dreamhost "grabs" the updated v2.05 and "diddles it" into the "one-click" system. They are generally pretty good about doing it quickly, especially if there are potential security-related issues being addressed, but you just have to wait for them to get to it.
