SYMPTOMS
Borland/Ashton-Tate has confirmed that dBase III version 1.0 and dBase III+ version 1.0 may cause your system to stop responding (hang) if HIMEM.SYS is installed.



CAUSE
dBase III 1.0 and III+ 1.0 include a feature called SuperLock that conflicts with HIMEM.SYS. According to Borland/Ashton-Tate, SuperLock is a copy-protection feature that allows you to install dBase III 1.0 and III+ 1.0 only once to a hard drive.



WORKAROUND
Adding the /CPUCLOCK:ON switch to the HIMEM.SYS line in your CONFIG.SYS file may resolve this conflict. If you are using dBase III or III+, add the following line to your CONFIG.SYS file device=[drive]:\[dir]\himem.sys /cpuclock:on where &quot;[drive]&quot; and &quot;[dir]&quot; indicate the location of the HIMEM.SYS driver.

The /CPUCLOCK:ON switch slows HIMEM.SYS, allowing it to wait longer for signals. This affects the speed of HIMEM.SYS, but not the system clock speed. Early versions of dBase were written for slower machines.
