Though after I put in the v1.2 patch, I went back to the part in the game ... found that there was still a problem with the mouse. But I went into fight mode, and did a whole heck of a lot of clicking all over the pillars.

I found out that where they expect you to click is quite a bit _below_ the image of the keyhole. Argh!!

Anyway, next time I'll try to remember about the space bar trick. ^_^

Thanks!
