>Does anyone know if Microsoft is doing anything to address the Insufficient Memory error on fast PC's? The error occurs when 600 or more items are used in list boxes only on PC's with processors faster than 166Mhz.

Paul;
I got burned by the list box bug and had to modify the code as a workaround. However, the work around turned out to increase system performance. I ended up adding a field to narrow down the number of record read into a cursor (or array) and display the contents of the cursor in the list box. This reduces the network traffic, and also more user friendly, since the user can narrow down the list of records.
