Just tried your thread...
First 2 posts come up blank in quote or edit.
The third post (Jorge's) is fine in both quote and edit.
Post 4 (your second) brings up your text in quote and edit but not the embedded quotes in that post.
Doesn't mean anything to me, but might help someone work out what's going on.
I suspected something to do with a bold font, hence the edit test but I couldn't see of the font was really bold... it didn't show up
