[RTTY] WF1B rebooting computer

[Dave NT6K]

After running in the RTTY Roundup I found that after
about 600 Q's logged with WF1B v5.02 my pent 120 w/64M
ram and DOS 6.22 was getting slow, so I upgraded to a
pent 233 w/64M ram and DOS 6.22.  What seems to be
happening now is that when I launch WF1B the program
reboots the computer.  I've tried the moslo.exe and
no matter what params I set it still reboots.
Anyone else had this problem?  Any ideas?
Going to a Windows based program is not an option.
