Application Errors and System Resources

I have created a 16 bit Delphi 1 package linked to BTrieve 5.10a via
Titan, using 16 bit Paradox and also using InfoPower 2.03.  I have
written the software as carefully as possible, and set up the BDE as per
many suggestions from the Internet.

I still get Application errors on the target system and lack of system
resources, which I never have on my development PC.

Any ideas
