I had an AMR database of 4,000 something directories. What annoyed me was that AMR seemed to freeze every other time I pressed a button and it often stopped responding once I pressed submit or modified the directories. Very annoying. I looked around and transfered my AMR database from an access database (what was installed by default) to a sqLite database. Now, NO MORE HANGUPS! Go to Tools > Export site list and export it as a .txt Go to File > Manage Database and create a new sqlite database. Go and import that txt into the new sqlite database. AMR will remove directories that are dead and you'll have a more lean directory list that is responsive.
