As I said, I am just chasing rainbows. The third SharedSection value is the size of the desktop heap for each desktop that is associated with a "non-interactive" window station. That space also has to include not only windows, but menus and memory hooks also. With all that is going on in the background, I just wanted to see if this value is different on the machines that are having problems. They may have installed something in the past that changed this value. Also, other programs can be using the user32.dll and using up the allocated space. Bryant said by making a change to the window size he corrected the problem. Do you see where I'm going here.

I am by no means an expert, but sometimes that helps to come at problems from a different angle.
