Based off previous question that I got a great answer from, I have around 30 forms and ADO's. I have changed all my code to opend and close all the connections after they grab their data. I am still getting machines that are locking up with 100% cpu usage. I have changed the priorities for the app to high but I am still getting machines locking up. There is nothing else on these machines although I did see a lot of services that have loaded. What else can I look for?
