Mark,

I find that as well. The unfortunate thing about that problem is, if there are many users accessing the same tables. Have you tried using a DO WHILE !EOF() loop and creating variables to access the table with the index file?? That seems to speed up the process for me. Before my USE statement I do a CREATE CURSOR and an INSERT INTO MyCursor before my SKIP statement. Don;t forget to set the indexes in the USE.
