Running legacy DOS program

[Bill]

I have an old DOS program that is based on a Paradox
database that I would like to run again due to it having
some useful historical information. It was last used on an
old 486 under Windows for Workgroups and was zipped down in
1996. I have managed to get it to go to its start screen
and even remembered the logon and password [admin for
both]. When I key in enter it then seems as if its going
to load but just sits there with the starting logo flashing
saying loading as it used to do when getting its self
going. In task manager the CPU goes upto 100% and the
memory used goes to 330Mb out of 512. Any ideas on what to
try next? I have played about with the memory settings etc
but I cant really remember what it would have run on on the
old 486. These days I can't remember my base memory from
my Himem, I seem to remember that it had plenty of buffers
set etc.

All help will be most appreciated.

Bill

Those old DOS apps eat up CPU while polling the keyboard, went through that
with some Clipper apps. You probably need to get a newer version of Paradox
and recompile the source code, or find a fix to the old version, which would
still require compling.
