Hmm I don't have the back button (lower left) in Canola. The thing is though... it had it when I first reinstalled it on my mmcboot yesterday. But now it seems to have dissapeared.

Edit: Interesting..

My Hildon_desktop's cpu usage is skyrocketing (I don't think it's due to Canola). But anyway, what's happening is without my 16 GB SDHC card in, the hildon_desktop cpu usage is at 10% (roughly around there). Load up canola, it loads fast and there's a back button.

Now stick in the card to my external slot, watch it skyrocket. Canola takes forever to load and no back button. Hmm..
