AmiQuote 3.25 as per @Sean request, STORES window position. So if you moved it somewhere in strange place it will restore there. These are consequences of features that being asked for.
Storing position assumes that customer does not shoot him/herself in the foot and does not move the window into outer space.
If you did, you need to delete
HKEY_CURRENT_USER\Software\TJP\Quote\WindowPos registry key
