More mysteries, minor and major:

Why did Gringott's Bank release money from Sirius' vault when he was 
a hunted fugitive?  Shouldn't they have told the MoM what he was up 
to? 

Does the money in Gringott's vaults earn interest?

Where did Snape go and what did he do at the end of GoF?  Did he try 
to get back into V's good graces, or what?

Why was Draco alone in the woods after the Quidditch WC?  Was he 
there with the intention to meet up with Harry, Hermione, and Ron?  
Was he actually trying to be helpful when he told Hermione to "keep 
that bushy head down"?

How did Crouch Jr. learn all the advanced magic that he displayed 
while at Hogwarts pretending to be Moody?  He was very young when 
sent to Azakban, then was under the Imperious Curse up until the 
QWC.  When did he change from the crying youth that Harry saw in the 
pensieve into an accomplished mage capable of hoodwinking a powerful 
magical object and successfully fooling Dumbledore for almost an 
entire school year?

What happens to an animagus' clothing and wand when he or she 
transforms?  

Where do female prefects bathe?

How do Quidditch players handle the Quaffle?  Is it caught and thrown 
or is it hit like in volleyball?

Why was it necessary to have such an elaborate plot to transport 
Harry to Voldemort in GoF?  It took nearly the whole school year, and 
there were many opportunities for a slip-up along the way.  Couldn't 
the ersatz Moody have kidnaped him by force, or slipped him a 
disguised portkey in a much easier, and more certain, way?

What happened to everyone's broom flying lessons after the first one 
described in PS? Did Hermione and Neville ever learn to fly one?

What happened to Harry's grandparents (both sets)? Were any of them 
victims of Lord V?

Do the Hogwarts toilets really empty directly into the lake as 
Moaning Myrtle implies?  Don't the merpeople object to this?

What's the deal with the stargazing Centaurs? Was there any 
particular significance to their observation that Mars was especially 
bright?
