   I have recently run into problems with some applications like
Lotus 123 release 3.1 and Novell Nondedicated Netware 286 that do not
preserve the 32 bit registers on 80486 system when they use them,
assuming all DOS PCs will use only 16 bit registers.  These usually
happen when these programs grabbed the system Timer interrupt, used 
32 bit registers and giving control to the BIOS and the BIOS returned
to the application that was using 32 bit regiters.  Novell seems to have a
patch for this problem.

  Send me an email if any of you know of such problems with any
popular software.  I will post the results.
