We solved our issue with Dynazip running on a Win98 PC. We are using many 3 third party tools in this app; SDT, INTL, Dynazip and Cryptor.
We found a conflict between Dynazip and Cryptor. Cryptor is a great utility for encrypting your dbfs (it really does work! - and with no performance issues that we can tell!). It was a call to a Dynazip dll function that was crashing VFP. But, we found that either utility worked fine alone.
The Xitech folks (Cryptor) sent us a new version of their dll which addresses this problem! Now all is working well together!
Thanks to the folks that responded to my earlier cry for help!
Thanks
