Yep. I've been working the Op.57. I can play it all at tempo from memory now, but it still has some parts that need to be beat into submission before I try to record it.
Which one are you working on?
Ah, the "Appassionata". That's one piece of music that really turns me on when I listen to someone play it live!
I am right now working on Op. 79, which is light-hearted and more like a sonatina compared to your Op. 57. But I like it and only started working seriously on it last week, so I still need to 'beat a few places into submission' too. Seems I have a bad habit of playing certain arpeggios with incorrect fingering and now that fact is brought to light very clearly for me in this particular piece.
