The problem also occurs when I do not load the UMBPCI driver. Stack overflow is likely occurring on mouse movement. Same with M$DOS and FreeDOS. FreeDOS sometimes displays a memory block violation or invalid instruction execution message.
When I load one of the drivers (JEMM, QEMM or EMM386) this does not happen. In CONFIG.SYS I have set STACKS=9,256
