The Osborne Executive destroys some of the Z80 alternate registers in
the CBIOS.  This could be the problem if your spelling checker program
uses them and does not save the registers when calling BDOS or CBIOS.
There is a fix for the Osborne Exec. users:

Filename			Type	 Bytes	 CRC

Directory MICRO:
TPATCH.LBR.1			COM	  1664  9126H

This is a program that patches the Osborne Exec. CBIOS so it preserves
the Z80 alternate registers.  It is run once when cold booting and
remains thereafter until the next cold boot.
