When I download photos into Picasa files, they import in first as a folder with a date name.  Once they are in a Picasa folder, I then select and move to another more generalized folder (i.e., Fall 2010), or rename with a verbal name (i.e., Christmas Party).  That dated folder then disappears from the list when the photos in it have been moved.
 
The problem arises when, from Facebook, I go to import photos, and go to Picasa folders.  What shows up at top of list are all the empty date folders that the photos went in originally as.  So even though these folders are “gone” from Picasa, they are really there somewhere.  I then have to scroll way down through folders to get to the named ones.
 
How do I delete these empty date-only folders, when I can't see them in the Picasa program!
 
Secondly, my “create album” screen in Facebook seems to be stuck.  I was in the process of selecting a bunch of photos (control select to get them all at once from Picasa folder), when it just froze up.  So now when, from Facebook, I go to create album, that same list comes up with the photos highlighted, but it won't let me continue to create nor cancel.  So the only way I can now download is through their “Simple Downloader” which only allows five photos at a time.   How do I get this to “go away?”
