Change the Size of Your Mouse and Keyboard Buffer

You sometimes may get an error message telling you that you have an overflow in your mouse buffer or keyboard buffer. When that happens, it means the buffer isn't large enough and you need to increase its size. To increase your mouse buffer, run the Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mouclass\Parameters, and find the MouseDataQueueSize subkey. The default setting is 100 (64 hex). Increase the decimal number to increase the size of the buffer; then exit the Registry and reboot. You may need to try several different settings until you find the right one.
To increase the keyboard buffer, look for the KeyboardDataQueueSize subkey in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kbdclass\Parameters. The default setting is 100 (64 hex). Increase the number to increase the size of the buffer; then exit the Registry and reboot. Again, you may need to try several different settings until you find the right one.
