Paul: Thanks for your most helpful and informative comments. BTW, What happens if I turn The Win98 Dos Box "Properties" > "Misc" > "Idle Sensitivity" slider all the way to 0% from "Low" (left)? Just for the record, here's the specs on my Win98 Dos Box. If you or anyone else sees anything that should be changed please let me know.

Besides the "Idle Sensitivity", which specifies how long Windows will allow the program to remain idle (waiting for keyboard input) before reducing the central processing unit (CPU) resources allotted to the program and enabling other programs to use them. Low idle sensitivity lets the program run longer before Windows reduces the CPU resources allotted to it. High idle sensitivity reduces the CPU resources allotted to the program sooner. If a program that is running in the background is not getting enough CPU resources, move the slider toward LOW.
You might also look into the "Dynamic Memory Allocation" setting. Make sure this check box is selected when a program uses text and graphic modes and you want to maximize the amount of memory available to other programs when the program is running. When you switch to the mode requiring less memory, Windows makes more memory available to other programs. When you switch back to the mode requiring more memory, Windows attempts to provide the memory. To ensure that there is always enough memory for Windows to correctly display the program in any mode, clear the check box.
You may wish to look into some of the FREEWARE products that do memory management, such as "RAM Idle". Use it to free up a selected amount of physical memory when the minimum level is reached. You can also use it to free up a selected amount of physical memory at a regular interval, and free up the physical memory manually as needed.
