Sorry,  things got busy around here.  By threshold limit I mean that we are now starting to see performance and speed issues, problems with memory resources on the server, queries taking too long to execute and locks being held too long.  I think most of the problems we are having are due to the design of the FE application where most forms have at least 2 combo boxes that populate with all the records from a large table, (one allows selection by id number, one allows selection by person's name).  As the size of the table continues to grow, performance is getting worse.  It's more an issue of a poor FE design than the fact that it is an Access FE linked to SQL Server.
