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.

I'm not arguing against it, just a different opinion.
Sure I see where you were going and do understand the value of tweaking this Reg item. Some viruses try to change this item to keep your machine from booting or to give you memory errors. I am not opposing your idea, sometimes its good to "chase rainbows" . It's surprising at how much runs under user.dll. You can find items associate with the dll by going to the CMD screen and typing "tasklist /m User32.dll". Works with any dll.
