>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.

Hi Paul,
I am having exactly the same problem, I have a client with
an aplication in 2.6a, the application has been running well
for almost two years, they just bought three new computers
pentiums 166 with 32 megs of ram and that is when problems
started, a simple "SHOW GETS" was causing the "Insufficient
Memory" error. My workaround to this was "Slow Down" the computer
by disabling the internal cache in the CPU. I know is a bad
solution but at least they are up an running.
Hope this helps.
