Hi all..stumbled onto this post a little late in the game but in response to those who have been having trouble putting the pallets "back together again" you all can try two things #1 hold down ALT and SPACE and click the palletes or #2 you can go to EDIT>>Reset Pallets in the menu bar. This should default them back to original positions. The shift move pallets is a documented feature covered in the manual and help files with the two above options listed as fixes if you don't like where they end up.
